Maximum RV Sizes: What’s the maximum RV Length Limits For State And National Parks?

• Last Updated: February 25, 2024
• 8 minutes read

There are 62 National Parks in the U.S., and these natural paradises encompass a diverse range of climates, geological marvels, and historic monuments.

Traveling by RV is one of the best ways to visit the National Parks, since you can often stay within or very near the park in designated campgrounds.

According to KOA, about 40% of all RV campers stay in state or National Parks when camping, instead of private campgrounds. 

However, not all National Parks allow RVs, and some have rough roads or lack the facilities to accommodate large motorhomes or long trailer campers. 

What is the best RV Length for Fitting into National Parks? 

If you are traveling with a towed vehicle such as a trailer or fifth wheel, it’s important to keep in mind that the maximum length allowed in most National Parks includes the camper itself and the truck or SUV you’re towing it with.

Unless you’re traveling in a motorhome without a second vehicle, your trailer will need to be about 10 feet under the length restriction to fit in your campsite along with the towing vehicle.

In this article, I have compiled a list of the most popular National Parks (with links) to provide a look at each campground’s vehicle length limits at-a-glance.

You can also get an idea for whether there are hookups or a dump station available at the campgrounds, and know whether you’ll need a reservation for a campsite or if they are first come, first served (FCFS).

FAQs About RVs and Camping in the National Parks

When you’re considering camping in the National Parks with an RV or trailer, there are some common questions that you may be asking. 

Are There Any State Regulations About RV Length I Should Know?

Although the National Parks are federally-operated property, they need to adhere to state guidelines and restrictions for the state in which the park itself is located.

Each state has its own regulations about the maximum allowable length of RVs. Keep in mind that some states refer to these vehicles differently, such as RV, motorhome, private motorcoach, house car, or even just ‘vehicle’.

Additionally, most states restrict the width of the vehicle to eight feet, including:

• New Hampshire
• Washington D.C.

Finally, you should keep your vehicle’s overall weight in mind as well. In some states, you’ll be required to have a Commercial Driver’s License (CDL) if your RV’s weight exceeds 26,000 pounds.

However, with the average length restriction in most National Parks being between 25 and 30 feet, you most likely will not surpass this weight and therefore you should be fine with a standard Driver’s License when operating your RV.

Do the National Parks Allow Class A RVs and Fifth Wheels?

In addition to length, it’s important to consider the type of RV you’re driving , since some models are larger (and longer) than others.

For example, Class A RVs are generally 30 feet or longer, and while they offer more luxury for living on the road full-time , they might not fit into many National Park campgrounds . 

Fifth wheels are the largest towable trailer campers available, and are often longer and heavier than standard campers .

Additionally, you must consider the total length of the trailer and your towing vehicle to fall within the length restrictions of states and National Park campgrounds, which might make an RV (with inclusive driving cab) preferable. 

Keep in mind that many National Parks can accommodate RVs and trailers (with towing vehicles) up to 40 feet in total length, but there are also several where the length restrictions are much shorter (around 20 feet).

So, for ease of getting around and camping in the National Parks, smaller is better and you’ll be safer staying away from Class A motorhomes and fifth wheel campers. 

what is the maximum length of rv allowed in national parks?

While the general average length of RVs allowed in most National Parks is between 25 and 30 feet, the overall average maximum length according to the U.S. National Parks Travel Guide is 27 feet.

However, there are a lot of National Park campgrounds that can comfortably accommodate longer RVs – even ones that are more than 40 feet long.

Always remember that for trailers, the total length must include the trailer itself and the truck or SUV that you’re towing it with.

Campground RV Length Restrictions In The National Parks

Most National Parks that have campgrounds allow RVs and campers, but some are tent-only.

The following guide lists only those campgrounds in the National Parks that allow RVs and trailers.

However, there are often private campgrounds near the National Parks that can accommodate RVs and sometimes have more amenities (i.e. full hookups ) if you are looking for a more comfortable, fully-equipped stay near the National Parks.

How to Find the Maximum Length for RVs at National Parks

While this article and the tables included here should help provide estimates of the maximum length of RVs and campers allowed in each National Park campground listed, you should always double check with the campground before making your reservation.

Sometimes, the camper length limit posted on the National Park’s website may be inaccurate, or sites that accommodate longer RVs might not be available. 

Your best bet to ensure your RV can fit in your campsite is to call the park and speak directly with a ranger or staff member who can confirm the details of your campsite.

Additionally, even if there is an RV length limit, sometimes there will be sites that can accommodate and allow for longer RVs and campers. 

The park ranger can also tell you about other information that might not be posted on the website, such as if the campground facilities will be unavailable during your trip due to renovations or repairs, or if they’ve recently added hookups to some sites that didn’t previously have them.

How to Measure Your RV or Trailer for National Park Campgrounds

Once you know the length limits for the National Park campground you intend to visit, it’s time to measure your camper to make sure that it will fit.

Start by referring to your owner’s manual or the RV manufacturer’s website to find the stated length.

This is usually bumper to bumper on an RV, or hitch to bumper on a trailer or fifth wheel.

Be sure to measure it yourself, though, especially if you have added storage boxes or other gear that you have loaded on to either end of your vehicle. 

It’s also a good rule of thumb to add a foot or two to your size just in case, to make sure you’ll have plenty of room to maneuver in your campsite.

However, if you have a longer camper, you might not want to do this, since it could rank your vehicle outside of the limit in some campgrounds.

Amenities at National Park Campgrounds

As you’ll probably note from this guide, most National Park campgrounds don’t have hookups for water and electricity, and are dry-camping, only.

Others have bathroom facilities with flush toilets, but no showers. However, there are some campgrounds with everything including hookups, dump stations, restroom and shower facilities, and even a camp store where you can buy firewood, ice, and other camping necessities. 

While it may be a bit of an inconvenience to camp without hookups, keep in mind that the whole point of the National Parks is to maintain the natural, rugged beauty of our park spaces.

By digging up the camp areas to provide sewer, water and electrical hookups and facilities, the parks system would be counterproductive to that goal. 

Like with the RV length limits, it always pays to call the park campground ahead of booking or arriving for your stay so that you can be fully prepared.

In addition, the campground may have sites with full hookups available later or earlier in the season, which are normally used by camp hosts that have left or haven’t arrived yet.

The park rangers can help you find the best spot for your needs, based on what’s actually available.

Summarizing RV Lengths for National Park Camping

Generally speaking, your RV or camper should be between 25 and 30 feet, maximum, to be sure you can fit into National Park campground sites and maneuver around the campground with ease.

However, some National Parks can accommodate longer or larger RVs and campers, but campsites for bigger vehicles may be limited or unavailable.  

It’s important to call the park before you book your site to make sure you’ll fit and still have plenty of room to enjoy your campsite.

The Ideal Travel Trailer Lengths for National Parks

Published on July 24th, 2020 by Levi Henley (Full-Time RVer, Content Manager and Media Specialist for RV LIFE)

Camping in U.S national parks go together like peanut butter and jelly. Our national lands are on every RVers bucket list as soon as they catch the desire to purchase one. Yet some of today’s RVs can’t get past the entrance gates because they exceed the best RV lengths for national parks.

The longest RVs allowed in national parks are between 25-30 feet in total length.

We’ll explore the many reasons for this limit and why it’s not always true. You’ll learn the best strategy to land that most sought after campsite at the best national parks for RV camping and how to get the best deal. Our research led us to a controversial proposed modernization plan to update the national park campgrounds that’s worth discussion.

RV Measurements Further Explained

National park spaces range in size between 20-40 feet. Some parks have 30 feet spaces with a couple of 40 feet spaces. As you can imagine those “prime real estate” campsites fill up quickly. Mostly, you’ll run across 30-foot spaces.

When they say 30 feet, they mean it. If you have a motorhome, a class C or small class A won’t be much of a problem. If you’re toading your passenger car, that’s where it becomes difficult. Your total length, including anything your towing must be 30 feet or less. There won’t be a place for your passenger car and the park rangers can deny your entrance.

Towable trailers have a similar problem. The average car, truck, and SUV measures between 14-17 feet. This means that the size trailer you need for national parks must be 16 feet or less from hitch to bumper. Small travel trailers , pop-ups, and teardrops are your best bet.

The majority of sites are primitive sites (no hookups). Most have a handful of spaces with either electric-only or water and electric. Full hookup sites do exist in certain national parks but they fill up fast.

The public parks usually have bathhouses that they maintain well but don’t expect a camp store, rental equipment shack on-site, or other amenities. Most either no longer allow campfires or have heavy restrictions on them. Whatever supplies you may need, pick them up ahead of time because the nearest store is going to be many miles away.

Road conditions are usually dirt. Smaller parks may have tight turns and other road conditions that make it very difficult for large motorhomes, fifth wheels , and travel trailers to navigate. It’s a safe assumption that back-in sites are going to be par for the course.

Current Conditions of Most U.S. National Parks

Most people think that our national parks started with the Antiquities Act of 1906, signed by President Theodore Roosevelt in his second term. Actually, in 1832, President Andrew Jackson signed a bill into law protecting land in Arkansas from private development.

President Woodrow Wilson created the National Park Service in 1916. This new bureau established the actual parks on federally protected land, gave it funding, and employed staff. The first camping craze of the roaring 1920s led the Park Service to establish campgrounds in many of the parks.

One of the major destinations for World War II veterans were national parks. Many new parks established during this second camping bubble had campgrounds added into the plans for the “Canned Ham” era RVs. With President Eisenhower’s new interstate highway system, the parks were affordable and easy to get too.

The point is, many of these campgrounds opened during time periods when RVs were smaller and less technologically advanced than the ones we have today. Those that have plumbed in campground utilities can’t update the campsites without destroying protected land.

Older campgrounds within the parks have lost space due to the growth of the natural plant life. The staff maintains the campgrounds through lawn care and other normal tasks, but cutbacks and preservation guidelines allow the skeleton crew to do so much.

Best Way to Make a Reservation

If you’re planning an RV national park road trip to see as many as possible, be strategic. The summer months when children are out of school is the busiest time for both state and national parks. The spring and fall are going to be the best times to find open campsites.

If your coach isn’t the best RV size for the public park, there are many private campgrounds surrounding the park. They have to compete with the park and the other private parks in the area, so you can expect them to have modern accommodations with full hookups, long campsites, and additional features.

Park Finder Website

If your goal is to stay at the park itself, a great strategy is to take advantage of both the website and to call them directly. The National Park Service’s Park Finder Website lists all of the U.S. parks, help you narrow down your search based on a number of different criteria, and connects you to their specific pages.

Once you know the details about the park and what length RV will fit in a parking space, call the ranger station directly. The campgrounds operate on either reservation only or first-come-first-serve (FCFS) depending on how busy and the time of year. The ranger can also tell you what campsites available based on cancelations or those that have left early.

America the Beautiful Annual Pass

A great money saver is the National Park Service’s America the Beautiful Annual Pass . Campground fees generally range between $30-$50 a night. The annual pass allows you entrance into the parks free of charge and other features that they charge per person.

A one-time charge of $80 will give the pass holder and up to 3 passengers in a private, non-commercial vehicle use of the pass benefits to all of the national parks and other public lands that are open to the general citizenry. Children 15 and younger are free of charge and don’t count under the three passenger limit.

Active military personnel can receive their pass free of charge. We thank you for your commitment to our country and thank you for your service.

There are three ways you can buy your pass. Either on-site at one of the national parks, over the phone, or through the USGS Store . The website allows you to printout a temporary pass until you receive your permanent pass via U.S. Mail.

Access Pass

Seniors (62 and older) and the disabled can apply for another type of pass. The Access Pass gives the additional benefit of a 50% discount on primitive campsites. Renewal is $20 a year.

What it Would Take to Modernize

What if national parks update their campgrounds? They could install every campsite with full hookups and wifi. Camp stores and restaurants would be available on-site. What if the national parks have RV size limits increased to 45 feet and the roads remade to accommodate RVs of those sizes?

There are modernization proposals floating around Washington D.C. that talk about doing this. Proponents and opponents are debating the protection of the ecological versus the economical advantages to the national parks.

The more famous parks like Yellowstone, Grand Canyon, and Yosemite are still popular. Yet some of the lesser-known parks that offer incredible landscapes and outdoor excitement are suffering from revenue losses. Overall visitation is slowly declining.

National Parks Are Still Worth the Trip

Taking your RV out to any one of our national parks can be a trip of a lifetime. You’ll see unique landscapes that only exist here in our country. The United States has the most diverse geographies on the planet. In our nation, you can climb mountains, journey through deserts, swim in oceans, and hike on glaciers.

This is the purpose of our national parks. Grab your family, pack up your RV and go explore.

• Set your watch to Old Faithul at Yellowstone National Park

State and National Park RV Size Limit (Length Restrictions)

• November 22, 2018 /
• RV Parking     RVing 101 /
• By R. Geraldi /

There’s nothing better than owning an RV — it gives you the freedom to go wherever you want without having to compromise on space and comfort. Therefore, it might be the perfect time to choose your home away from home. However, when choosing an RV , there are some things to conside r , especially if you’re planning a tour in one of the national or state parks.

Namely, before you make a purchase, you should inform yourself about the US national parks RV restrictions and campground RV length restrictions. What’s more, if you already have an RV, this information will still prove useful — you don’t want to plan a trip only to find out you can’t camp out at your chosen destination because your RV exceeds the national park RV size limit. So what’s the max RV size for national parks?

What Size RV Is Allowed in National Parks

If you’ve gone with the attitude “the bigger, the better” when buying your RV, you might have to forgo trips to national parks. In fact, there are some quite notorious rules when it comes to national park trailer length limits.

As you know, your RV can be anywhere from 12 to 50 feet long. However, not all of them can fit into the guidelines that regulate the maximum trailer length for national parks.

Still, while having a small RV will make sure you can get practically anywhere, even if you aren’t ready to sacrifice your comfort for access rights, huge RVs can still get into around half of the national parks that allow RVs. Therefore, you might have to sacrifice the location of your camping, if you’re looking to buy a 41-foot beauty.

Best RV Size for National Parks

Generally speaking, the best RV lengths for national parks are between 12 and 25 feet. If your beauty is anywhere within this range, you’ll be able to get into pretty much any national park in the US. However, keep in mind that some parks don’t allow RVs at all and are “tent only.”

Almost all of US national parks RV size limits will allow a 12-foot, a 9-foot, and even a 25-foot RV on site. However, as the size of your camper increases, the chances of you getting onto a National Park camping grounds diminish.

Campground RV Age Limit

The US national parks RV restrictions sometimes also include age restrictions. Some campgrounds that are trying to maintain a luxurious look only allow new RVs on site. Therefore, you might see a sign that says that your RV isn’t eligible for a long-term stay if it’s older than ten or even five years. This is a real issue for enthusiasts who love old-time Airstreams, for example. However, this isn’t a problem that you’ll run into very frequently.

What’s more, since the campsites with age restrictions are a few and far between, if you run into this problem, you can always just move along. Another campsite is probably around the corner.

The Maximum Length of RVs in National Parks

The maximum trailer length for national parks varies from park to park. Some parks will even permit you access regardless of your RV size. Here are the US national parks RV size limits for the four biggest and the most frequently visited national parks.

Glacier National Park RV Size Limit

If you’re a proud owner of a massive RV and are headed for Glacier national park — you’re in luck. As long as your RV is 35 feet long or shorter, you’ll be granted the permission to enjoy most of their campsites. Still, it’s important to keep in mind that only seven out of thirteen Glacier campsites allow RVs at all.

This gem of pure Montana wilderness will be a perfect short-term home for your RV. However, not all seven campsites allow massive RVs. The Rising Sun campsite, for example, only allows RVs that are 25 feet long, while the Apgar campsite has above average campground RV length restrictions and will allow you to camp out in your 40-foot RV.

Yosemite National Park RV Length Limits

Arguably the most popular and the most famous national park, the Yosemite has ten campsites that accept RVs.Yosemite has a wide range when it comes to the maximum length of RV in national parks.

However, like many US national parks RV restrictions, the restrictions in Yosemite also usually differentiate between the RV size and the trailer size. Therefore, that’s something to keep an eye out for.

For example, in Yosemite Valley, you will be granted an entrance if your RV is not longer than 40 feet , provided that the trailer itself is no longer than 35 feet. On other campsites that accept RVs, the campground RV length restrictions are 35 feet for RVs and 24 feet for the trailer length.

Yellowstone RV Length Restrictions

Luckily for all us RV enthusiasts, Yellowstone, the first national park in the US, has 12 campsites, and they all allow RVs on site. However, only one campsite offers a place for massive RVs.

Fishing Bridge RV Park is a famous destination among RV owners. It allows a combined length of more than 40 feet when it comes to the RV and the towing vehicle. That means that you can easily get in with a 40-foot RV. The length of your towing car doesn’t count , as you can park it beside the trailer (instead of parking it in front of the trailer).

However, other campsites have a different set of campground RV length restrictions — the maximum length is 40 feet, but that includes both the length of the RV and the length of your towing vehicle.

Zion National Park RV Length Limits

If you have your heart set out for the national park Zion and you own a large RV, you won’t be happy with the size guidelines. Namely, the maximum length of an RV in national parks such as Zion is around 19 feet. Furthermore, all campsites allow a maximum of two vehicles — your towing vehicle and your trailer or RV.

Do you plan on heading to the Grand Canyon or the Bryce Canyon after your trip to the Zion national park? If your vehicle is large, then you’ll need to obtain a special tunnel permit. Namely, you need a tunnel permit if your vehicle is wider than 7 feet, 10 inches and taller than 11 feet, 4 inches. What’s more, if your RV is longer than 40 feet or the combined length of your vehicle and trailer is longer than 50 feet, you won’t be granted access to the Zion-Mount Carmel Tunnel.

Maximum RV Length at State Parks

There isn’t much of a difference in maximum RV length allowed when it comes to national and state parks. What’s more, state park RV length restrictions also vary from park to park. That means that you can find a suitable location no matter what your RV length is.

Texas State Parks RV Length Limits

The Lone Star state has many state parks, many of which allow RVs on their campsites. However, if you own a huge RV, there’s a good chance that you won’t be granted access to a great number of them.

Therefore, keep in mind your RV length while planning your trip. If you are headed for the Texan fan-favorite, Radcliff Lake Park, or to Oakland Park, you might not have any problems finding a suitable campsite. You can enter these parks even with a monster RV of a combined length of 50 feet. However, parks like the Jackson Creek Park only allow RVs up to 25 feet in length.

Maximum RV Length — Oregon State Parks

Oregon state parks have an average, general rule that the combined length of your towing vehicle and your RV can’t be over 40 feet. That means that most RVs that are over 30 feet aren’t allowed.

However, that’s not the case at all campsites. Still, if you have a 35-foot RV, you might have trouble finding the space. However, some parks and campsites allow you to unhook your RV from your vehicle. That way, you can park the vehicle besides the RV. That might be a way around this rule.

It’s important to note that Oregon state parks and their campsites have a very wide range of state park RV length restrictions. On some campsites, the maximum length goes up to 80 feet. For example, the regulations aren’t so laid back in California as they are in Oregon.

California State Park RV Length Limits

California state parks allow for 25–30 feet long RVs, on average. Most campsites were originally designed for tent camping. Therefore, they don’t have enough room to accommodate huge RVs and their towing vehicles.

However, in California state parks, much like in Oregon, the campsites have regulations about RV sizes that vary. So, for example, the D. L. Bliss State Park and the Tahoe state park only allow RVs that are a maximum of 18 feet long (15 feet long trailers).

On the other hand, if you have a large RV, you still have options in California. Bolsa Chica State Beach allows trailers up to 40 feet long. Meanwhile, Emma Wood State Beach allows RVs as long as 45 feet.

Florida State Park RV Length Restrictions

Florida is a very camping-friendly state. Therefore, a lot of state parks allow RVs, and many of them will accommodate your large RV. Campsites in Florida also have a wide range of state park RV length restrictions. Some of them only allow vehicles that are 10 feet long. However, others allow massive rigs of 104 feet in length.

In fact, in Florida , the motto is — the bigger, the better. At least when it comes to the RVs. Thirty state parks allow RVs that are over 45 feet long. Meanwhile, twelve parks allow rigs that are between 36 and 40 feet long. Only four parks allow for vehicles up to 35 feet in length.

Washington State Park RV Length Restrictions

Washington is a gorgeous state to camp in. In fact, you can choose one of almost 50 state parks to set your rig in. However, not all of them have the same state park RV length restrictions. The average size limit in the state of Washington is between 30 and 35 feet . However, you can find campsites that allow RVs up to 60 feet in length.

What’s more, if you have a genuinely huge RV, you can explore the option of private campgrounds. They are not that rare, and most of them have size limits that allow for bigger RVs. In fact, most of them allow the length of 60 feet or more per RV.

A Few Parting Words

US national parks RV restrictions vary greatly. Therefore, if you are looking to buy an RV, make sure you include these restrictions as a deciding factor. However, if you already own an RV, this information might help you plan your next adventure. It’s crucial to know if you can camp out at a certain park or not.

Things aren’t much different when it comes to state parks as well. It seems that Florida is the most camping-friendly state. However, you should definitely check national park trailer length limits and state park RV length restrictions no matter where you plan on setting up camp next.

RV Size Limits for National & State Parks (Helpful Guide)

The state and national parks in the United States are some of the first places people want to go in their RVs.  In fact, many people buy their RVs exclusively to use in state and national parks.

What’s the maximum RV size for state and national parks?  The maximum recommended size RV for national parks is 29 feet with this number holding true for most state parks as well.  The reason for this is that many state and national parks will not allow campers that are longer than 30 feet.

Let’s take a look at exactly what you need to know about bringing an RV to a national or state park in the United States.

Table of Contents

National Parks And RV Sizes

Are you planning on buying an RV to take to both state and national parks?  If so, you might be interested in knowing that not all RVs will fit in the camping spots that these places have to offer.

Each national park will have its own size restrictions when it comes to what size RV you can bring in.  Many of these will have combined restrictions meaning the length cannot exceed the length of both your towable camper and your tow vehicle.

If you have a motorhome without a tow vehicle , you’ll have more space to work with.

Also, keep in mind that there are usually multiple campgrounds within a national park and each campground may have different size restrictions.

For example, the Great Smoky Mountains National Park has campgrounds in ten different locations.  Some of these campgrounds do not have any size restrictions while some do not allow RVs in at all.  The rest fall somewhere in between with Abrams Creek only allowing RVs measuring 12′ long and Smokemont allowing RVs as long as 40′ long.

Here is a list of RV lengths allowed by each national park in each state:

You’ll notice that on this list there are some national parks that were listed more than once.  This was intentional as some national parks encompass multiple states.

You’ll also notice that if you have a motorhome that is under 30 feet long, you’ll be able to access any national park that allows RVs.

However, if you’re towing a vehicle behind you or are towing a towable camper, 30 feet might just be too long.  In this case, you’ll have to find out how long your tow vehicle is and then tow a camper that is short enough to fall within the 30-foot length restriction.

Remember, if you’re towing a fifth wheel , you’ll have some additional space because part of your camper will reside over your truck’s bed.  In this case, you’ll want to hitch up your camper and measure everything together.

Tiny Houses and National Parks

A tiny house is essentially a towable camper so you’ll be able to take your tiny house into a national park but you’ll need to make sure it meets the size restrictions of the park you’re visiting.  Just keep in mind that RVs are usually much shorter than tiny houses and a tiny house that is too tall may run into trouble in some national parks.

Also, keep in mind that the access roads in some national parks aren’t always smooth.

Some tiny homes are not built to go on dirt roads so you’ll want to make sure your tiny home is prepared for off-road conditions before you decide to take it into a national park.

State Parks And RVs

There are over 1,500 state parks in the United States and many of them allow camping.  Some of these state parks have multiple campgrounds within the park and all of them have their own restrictions.

As much as I’ve dreamed about camping in all of the state parks in the United States, it isn’t a realistic goal for anyone who doesn’t want to dedicate their entire life to it. Even if you could visit a different park every single night of the year, you’d still end up devoting over 3 years to your trip.

For this reason, you shouldn’t buy an RV based on being able to camp in all of the state parks in the country.  Even if you did, you might find that you end up purchasing multiple RVs over the course of your journey and some of the states may change the rules before you actually get to them.

In this case, a better idea is to look at the state parks you think you’ll be visiting most often so that you can buy an RV that works for those parks.

My advice would be to look up the information on each state park within an hour or two of your house.  These are the campsites that you’ll be able to visit each weekend without having to take time off from work and they’re the ones you’ll probably end up visiting the most.

How to Learn More about State Parks in Your Area

Each state park has its own website that you can use to research each of its state parks.  Some websites are much better than others but most of them will at least give you a list of parks as well as contact information.

If you’re unsure about the state park’s requirements, why not go ahead and visit them yourself?  This way, you’ll be able to take a look at the campsites and talk to the rangers on site. 

You’ll also be able to get a feel for the park to see if it is a place that you’d like to spend a lot of time in.  If it isn’t, you don’t want to plan your RV purchase around visiting it anyway.

4 Other Restrictions do I Need to Consider?

Size isn’t the only RV specification to think about when buying an RV for the state and national parks.  You may also want to think about water tanks, bathroom facilities, and power supplies.

Other Items to Consider

• Water requirements.
• Bathroom facilities.
• Power supplies.
• Temperatures.

1) Energy Restrictions

Did you know that some state and national parks do not offer full hookups?  In this case, you may want to consider getting an RV with a great alternative backup power supply.  This is especially true if you have a health issue.

For example, you may need to have an energy source to power a CPAP machine.  You might also need to have the power to run a refrigerator to store your medicines.  People camping in the desert might want to think about getting an RV that has solar power built into it.  Others might want to think about getting an RV with a nice generator built into it.

Need more information on RV electricity?  Take a look at my post titled, “ Do RVs Need to Be Plugged In “.  This post will give you more details on getting electricity, water, and even cable and Internet at your campsite.

2) Temperature Restrictions

Some state and national parks are too cold for some campers.  Does the RV you’re considering have heat?  If so, is this heat source usable if you don’t have electricity?  For cold weather state and national parks, you’ll probably want an RV with a built-in gas or diesel powered furnace.  This way, you’ll be able to heat your RV even if you’re at a cold campsite without electricity.

Additionally, you might want to consider buying a 4-season RV.

These RVs are insulated better than 3-season RVs so you’ll be able to retain your heat longer than you can in RVs that are not insulated very well.  This will save you money on fuel and will increase the amount of time you can camp before having to drive out of the park to get more fuel. Here’s all you need to know about RVs and insulation .

3) Bathroom Facilities

Not all parks have dump stations or flush-toilets.  Are you OK with using pit toilets?  Are you healthy enough to dig your own toilet if you have to?  When choosing an RV, you might want to look into the bathroom facilities at the parks you plan on visiting so that you can buy an RV that meets your needs.

For example, if you’re going to be camping in a park without dump stations, you might want to buy an RV with a large black water tank .  This will give you the ability to stay longer without having to worry about overfilling your RV’s sewer system.

Alternatively, you might want to think about adding a cassette toilet or dry toilet to a camper that does not have bathroom facilities.

Of course, you might find that the opposite is true as well.  Some state parks have great bathroom facilities with flush toilets, hot showers, and even laundry facilities.  If you’ll be visiting these kinds of parks, you won’t have anything to worry about at all.

4) Water Requirements

While we’re on the topic of plumbing, we should talk about water requirements.  Some desert parks might not have any water readily available to you.  In this case, you might want to think about getting an RV with a large freshwater tank.

In other cases, you might not have to worry about water at all.  Personally, I can’t think of any parks or campgrounds in the northeast that do not have a source of water that you can access.  For people camping in this part of the country, a dry camper without water storage might work just as well.

For more information on RV plumbing, take a look at my post titled, “ Do RVs Have Water Tanks and Water Heaters “.  There you’ll find information on tank sizing and tank usage.

Alternative Options

Still searching for a camper that will meet all of your needs everywhere at all times? You might want to consider a truck with a truck camper and a towable camper.  This gives you flexibility since you’ll essentially have two different campers to use depending on the campground you’re visiting.

You’ll also have a standard vehicle so you’ll end up with a setup that offers you three different options.

For example, you could tow your large camper to places like Zion National Park where there aren’t any size restrictions to worry about.  Then, when you wanted to visit a park like Death Valley, you could leave your towable camper behind and load up your truck camper.

Another option might be to buy a small motorhome as your tow vehicle.  Some people will buy 20 foot long motorhomes and lightweight campers to tow behind them.

Check our complete guide to tow-cars for RVs .

In this instance, the person has a small motorhome that they can take on weekend trips and to parks with heavy restrictions and they can tow along their larger camper on longer trips and to parks with loose restrictions.

What Size RV Should I Buy?

Unfortunately, there really isn’t a one-size fit all solution to buying an RV for state and national park camping.

However, this doesn’t mean you can’t buy the perfect RV for your particular situation.  The key point to keep in mind is that there are a lot of state and national parks and you won’t be able to visit them all at once.  This is great since this offers you many years of camping fun and you may even get the chance to buy multiple RVs over the course of your life with camping.

I’d suggest that you start your journey by deciding on which state and national parks you’ll be able to visit within the next few years.  Then, choose an RV that meets your needs as well as the requirements of each state and national park within your plan.

In a few year’s time, you can plan a few more years of camping trips and buy another RV that is perfect for these new trips that you’ll be taking.

If you end up having to decide between a few different RV options, your best bet is to buy the smaller of the two.  There are usually maximum size restrictions but there are never minimum size restrictions.

Buy a smaller RV and you’ll give yourself more camping options in all of the parks as well as the campgrounds outside of the parks that you may end up staying in.

Additionally, you’ll save money on RV storage and insurance so you’ll end up winning in multiple ways.

If you are looking to buy an RV, You need to read these tips first: Our very best buying tips for RVs and Motorhomes .

Plan carefully before you buy your RV and be sure to do your own research on the areas that appeal most to you.  Evaluate your own individual needs and you won’t have any trouble finding the perfect RV for your next trip.

2024 Ultimate Guide To National Parks RV Length (Huge Time Saver!)

What is the Best Length For An RV In The National Parks?

If you are planning a national park vacation, it’s important to know if your RV is allowed in the parks. Each National Park will have RV length limits depending on the configuration of their campsites and most parks were developed before the more modern RV lengths came along. 

The average size of RV sites is 27 feet nationwide. Therefore t he optimal length for an RV in the National Parks is 25 to 30 feet.  Most National Park campgrounds will have spaces that will fit this length. Sites vary park by park and campground by campground, so always check directly with the park office prior to booking a site. 

If you are planning a national park vacation , it’s important to know if your RV is allowed in the parks. 

The rules for length restrictions on RVs vary widely by location and can be confusing if you aren’t familiar with them. This is especially true when considering that many of the most popular National Parks have unique regulations about how long your RV can be. Some parks allow any size motorhome, while others only permit small trailers or even motorcycles! 

We put together this list of information to help make sense of these different lengths limitations so that you don’t waste time trying to find out what’s possible for your trip! You don’t want to show up for your site with a rig that is too long to fit, and it is considered poor campground etiquette . 

Below are the stated National Park RV length restrictions for every National Park that allows RV camping. Please use it as an idea and then do some extra research (preferably on the phone) to get situated.

We have endeavored to clarify as much confusing information as possible by direct contact. (One park stated 30 ft restrictions on travel trailers and 21ft restriction on 5th wheels!) We have also included prices, and basic services for each of the National Parks RV campgrounds . 

If this is your first tour of the National Parks, I would highly recommend this book .  It will tell you what to look for at each National Park (we still recommend you do your own research), but this will help you with planning your trip.  

“The national park idea has been nurtured by each succeeding generation of Americans. Today, across our land, the National Park System represents America at its best. Each park contributes to a deeper understanding of the history of the United States and our way of life; of the natural processes which have given form to our land, and to the enrichment of the environment in which we live.” George B. Hartzog Tweet

Older National Park Campgrounds May Be Too Small

America loves it’s National Parks. KOA research shows that 40% of all RV Campers stay in National or State Parks.( 1 ) But as RV’s get larger, fitting them into 1950’s and 60″s era campgrounds is becoming more and more difficult with National Park RV size maximums. Many people (including us) would love to stay within the National Parks but simply cannot fit into the sites with a large RV.

If you are camping in a smaller teardrop or pop up camper, you probably do not have much to worry about, but with the increasing size of most travel trailers and fifth wheels, some care must be taken when planning a site. 

Most National Parks that have RV campgrounds do not offer any kind of hookups. So it is dry-camping only . There may be some types of amenities, like a dump station, vault toilets, etc, but sites do not have hookups in most cases. National Park RV camping accommodations as a general rule are a bit sparse.

You have to remember that the whole idea of our National Parks is to celebrate our natural spaces, so clearing and digging up large sites within those natural areas to allow for sewer hookup’s and 50 amp electrical service, or even to cut through roads to accommodate 40+ foot long motorhomes, causes a great deal of heartburn. 

That being said, many parks are making upgrades where possible to accommodate longer RV size limits as well as the demand for hookups . 

Which National Parks will  work for your rig? We have done the legwork for you and compiled a list of every National Park campground that allows RV camping , and the information necessary for you to make your decision. 

If you don’t have an Annual Pass for the National Parks, I highly recommend you pay one annual fee , which will get you into all of the USA National Parks.

Campground RV Size Restrictions

Every National Park has RV length restrictions. There does not seem to be any consensus anywhere, nor an authoritative resource to tell us how sites are measured. Typically the length restriction will be for  camper AND tow vehicle , so the allowable length for a trailer will be shorter than for a motorhome by about 10 feet. 

Our best advice is to take a look at the list below and use it as a guideline, but not as a bible. Nor should you use ANY online resource as authoritative. We strongly recommend that you do the following:  

Call The Park:  We have found that at the end of the day, no matter where you are trying to camp,  you ALWAYS do better by speaking to someone right there at the park. You will get first hand information that will often times contradict what you read or hear online. For instance if you are just staying overnight and do not wish to unhook, make sure you can get a site long enough for the whole shebang. 

When we were staying out at  Yellowstone  last year, we stayed outside the park, at  Henry’s Lake State Park  (AWESOME park.) During our 2 month visit, we stopped around to see several of the Yellowstone campgrounds. Keep in mind that this was mid summer, when anyone would tell you it is next to impossible to get a site within the park.

While visiting the Mammoth Springs area, we noticed that the campground there had quite a few empty spaces. We stopped to speak to the ranger at the gatehouse, and she told us that they had been experiencing quite a bit of vacancy over the last couple of weeks. They usually got several walk-ins during the days, but each morning many left. 

We also noticed that, even though the park has a maximum RV length of 30 feet, there were a large number of sites that would, and WERE holding RV’s much longer than that. The ranger told us that the restriction was there, but they often put larger rigs into the park without a problem.

Another story: When we visited  South Dakota , we stayed at a Angostura State Recreation Area, a huge, beautiful facility on the Angostura Reservoir. The campground offers electric only sites at VERY affordable prices. When I called them on the phone to get some information, I got some surprising news. 

The ranger who I spoke to told me that they did in fact have a few full service sites that were used by the on site camp hosts. Since it was late in the season, some of the hosts had been released and left. So there was a fully paved ADA site with full services and a built in stone fire-pit available if we wanted it. (We wanted it) I think we paid about $25 per night for the site. All because of a phone call. 

The point is this: call the park. ALWAYS. Get first hand information from someone on the ground , who does this every day. You never know what will happen.

You can get most of the information you need for visiting National Parks online or at the park.  If you want all of the information you need in one spot, I highly recommend this book. The pictures are beautiful, and you get a good idea of what there is to do and see!

Let’s take a look at the travel trailer restrictions in National Parks and the RV length restrictions by state .

Gifts For National Park Lovers

Looking to visit all the National Parks within the US? Well, this National Parks Bucket List art is just what you need to track your park road trips!

Each National Park has a camera icon next to the parks name. As you visit these picture-perfect parks, use the included push pins to pin your list within the circle of the camera lens to show you have “captured” that park. Makes a fun way to track and show off your National Park Adventures

I absolutely love these and will be getting one (or two) as soon as I have a wall large enough to fit them on.  The best part is you can get them personalized.  What a gift for all nature loving peeps!

How Do I Measure My Rig for Campgrounds

All of this being said, you still need to find some earmarks to use in selecting sites for your rig. Some people say that they “add a few feet” to the stated rig length so that they always have extra room in their campsite. If you have a smaller rig, feel free. For us with a 38ft rig, I would never do this. It is hard enough to find sites in some parks to fit us so I wouldn’t want to eliminate a 39ft site because I said my rig was 40ft. 

Our recommendation is this: go with the stated length of your rig, which is usually written in the model number of your rig. Then talk to someone in person so you can discuss slides, width, etc. You will almost never go wrong.

It’s a shame you don’t have a donate button! I’d without a doubt donate to this fantastic blog! I suppose for now i’ll settle for bookmarking and adding your RSS feed to my Google account. I look forward to brand new updates and will talk about this blog with my Facebook group. Chat soon!

Thanks a ton for the vote of confidence!

Hi! Question about trailers. Is Max length for the combined length of a trailer and the truck towing the trailer? Or just the trailer? Thank you!

Great question Julie. As a general rule, the Max Length is for just the RV parked in the site. In other words a 30ft trailer is the same as a 30ft motorhome. That being said, ALWAYS call the park while planning and double check. You would think there would be a consistent dimension protocol throughout the NPS but there is not. Each park has it’s own way. Besides that- talking to a real person will almost always be worth the effort- no telling what you will find out- details that you would never see on the park page. We once stayed a couple of weeks at Angostura Reservoir in South Dakota (near Mt Rushmore and Custer State Park .) . It is a State Recreation Area with several campgrounds- all of which are “electric only.” Normally we would not have stayed there but I called to talk to them and found out that, since it was late in the season, some of the Camp Host sites had been vacated. The site we got was full hookup, AND was an ADA site. This meant it was fully paved and included a built in fire pit. One of the nicest site we ever had.

Thanks for this fantastic information! I am a beginner in the research phase (have never camped yet) so this may be a dumb question but.. With regards to maximum length, you mention “standard”, “premium”, and “combined”. Can you explain exactly what this means? Thanks.

The terms “Standard” and “Premium” usually refer to the size of the site, or the amenities available. Since there are no consistent description rules about sites throughout the NPS (each park writes it’s own language) I would recommend always contacting the park in question directly to make sure you have a clear understanding.

The term “combined” usually refers to an RV and tow (or towed) vehicle. In other words the total combined length of your entire rig. Again -double check with the park directly.

It would be nice if the state where each park is located were included.

HI Norman, Not sure I am following- the article is organized by state- alphabetically.

We are planning our retirement way ahead and looking to get a 39 ft Class A Toy Hauler for an ATV (or two) while pulling a 21 to 25 ft boat. Do you have a list of parks with trails for riding ATVs and/or campsites with boating?

We have not done a list for those specifically, however, the NPS does have a page listing parks for watersports: https://www.nps.gov/subjects/watersports/visit.htm For the ATV trails- I do know if there is a page specifically for that, but you can try the “Search By Activity” page and may be able to search. https://www.nps.gov/findapark/advanced-search.htm?a=8&p=1&v=0

This is such a comprehensive list. Thank you for taking the time to put in so much work for all this information.

Awww so glad you enjoyed it Tonya, thanks for stopping by.

Hello, just wanted to mention, I loved this blog post. It was helpful. Keep on posting!

Redwood National Park does have 3 camogrounds with RV camping. It is the only national park co-administered by the state parks, so the campgrounds are listed on the California State Park website.

Jedediah Smith Redwoods SP Del Norte Redwoods SP (Mill Creek Campground) Prairie Creek SP

RV max length is 25′ and trailer is 21′ feet for Jed Smith.

Thanks for the heads up- UPDATED.

I am a bit confused on whether to include the length of the tow vehicle or not. In one place you mention that the Restriction applies to Length of RV + Tow Vehicle, but in a comment you mention that MaxLength only applies to the Length of the RV. Which one is it?

I believe the mention of both RV and tow vehicle was about the term “combined” length. It is a bit confusing and you can believe me, it was frustrating trying to find consistency in putting this article together. The NPS does not seem to use any kind of consistent terminology so what I did here was to be as consistent as possible, and tell people to ALWAYS double check with the park you want to stay at. You will get better specific information that way.

However, for purposes of the article, if there is ONLY one MAX Length mentioned- it is for the RV. On some there are 2 lengths- one for RV’s (drivable) and one for trailers (TT and 5ers). Obviously that does not include the tow vehicle since the trailer lengths are always shorter. On others they actually give a “Combined” length which obviously includes both. I hope that helps, but really… CALL THE PARK!

Hello, Great article and reference information! We are a family of 6 considering our very first RV trip so forgive my newbie question. Do the restrictions only apply if you are staying in the park or does it also apply to visiting? For instance, can we drive a 32 foot long RV into a park that can only accommodate 27 foot long RV’s as long as we drive out before the end of the day? Thanks, Jon

The length restrictions we mention in the article apply to campsites, so only if you are staying. Just double check that the park has day parking that will accommodate you. Most do, but always check.

The topic of travel is very much in demand! Traveling is a great joy for every person! Thanks for the article!I agree with this information! Everything is great! The article helped me!

Thanks, hope it was helpful!

Planning ahead as buying our 35′ Pace Arrow next week. When towing car exceeds length is there room on campsite park or even on campground property? Thanks for all your efforts.

Many times yes, just call ahead and check. Usually there will be a parking area nearby.

THANK YOU SO MUCH FOR TAKING THE TIME TO WRITE ALL OF THIS INFOMATION. WE JUST PURCHASED A MOTORHOME AND DON’T KNOW ALL OF THE IN’S AND OUT’S YET, SO THANK YOU AGAIN, MUCH APPRICIATED.

The mountains are calling, and I must go. John Muir Tweet

You’ve been summoned.

Drawn to the majesty of the alpine Rocky Mountains, the grandeur of Acadia, the balds of the Smokies or the alpine lakes of Glacier. National Parks are America’s greatest idea, and you can’t resist the temptation of Mother Nature’s siren song.

Visiting a National Park in an RV allows you an up-close-and-personal experience with the park’s weather, scenery and wildlife. 250-350 million people visit America’s National Parks every year. Most travel by automobile, but you know the secret: the best way to experience the parks is by RV!

But … how big can you go?

Because in case you don’t know, most National Parks have restrictions on maximum RV length.

Now, this can (and should) actually be broken down into several questions:

• How big of an RV do you need for the trip you want to take?
• How heavy and large of an RV trailer are you comfortable driving?
• How long of an RV is recommended for National Parks?

Let’s talk about Question Number Three.

The optimal length for a towable or motorhome RV in a National Park campground is 25-30 feet.

That’s the short rule of thumb: I f you want to visit lots of National Parks for your bucket list, a safe bet is 30 feet or less. Scroll down to learn more about whether this applies to just your RV or if it also includes your tow vehicle.

Important Things to Know!

• Many parks, particularly the more popular ones, commonly allow RVs up to 40 feet in total length.
• Some parks even allow RVs up to 50 feet – or no maximum length whatsoever!
• Campgrounds may have separate length limitations for motorhomes and trailers (e.g. motorhomes 40 feet, trailers 35 feet). When this is the case, allowable length for trailers is usually 5-10 feet less than motorhomes.
• RV length limitations often (but not always) jump in increments of 5-ft (e.g. 25, 30, 40 ft allowed).
• On the smaller end, some NPS campgrounds limit RV length to 22-25 feet (or even smaller!). These campgrounds tend to be more remote, smaller, without any hookups, and may require high-clearance vehicles for access.

As a rule, the more rugged the terrain, the more limited the RV length.  

And don’t forget about those slide-outs! Check width restrictions as well. Restrictions may vary by campsite due to tree location and turn radius. When in doubt, call ahead.

If your RV is up to 35 feet long, you can usually find a spot at most National Parks.

According to Camper Report, RVs up to 35 feet in length will fit in 73% of National Park campgrounds. And since many Parks have multiple campgrounds, there’s a pretty good chance you’ll find a home for the night.

Your odds are still decent up to 40 ft. It is reported that roughly half of all NPS campgrounds accept RVs up to 40 feet in total length. You’ll be restricted to more developed campgrounds in more popular parks, however, so the odds of reserving a spot become slim. Everyone wants the same spot you do!

Camping opportunities take a nosedive after 40 feet. Only the odd NPS campground here and there will accept behemoth RVs. Even where no maximum length is posted, you’ll find anything 40 feet and over will be a tight squeeze. You may find yourself dammed up on a hairpin turn or in a zero-clearance parking spot.

Call ahead! Some sites have “fudge room.”

No one really likes this answer. Unfortunately, it really is the best advice.

Some sites only allow 30-ft combined length, but guess what?! – there’s room to unhitch and park beside your RV (but you’re only allowed up to two vehicles per site, remember). 

Meanwhile, other sites only allow 30-ft combined length – period. No room to park beside your camper. Sorry.

But maybe others have a campground parking lot that’s a 100-yard walk away!

Or maybe there’s a public parking lot that’s a 5-15 minute drive away. 

Also, let’s just say that some of the numbers posted online by the National Park Service aren’t known for their accuracy. Or maybe they haven’t been updated in 8 years. Who knows?

So do yourself a favor and call ahead! Talk to a park ranger or campground host and get the goods. You may be pleasantly surprised (or you may avoid a tremendous headache).

Combined vs. Total Length?

Don’t get confused by combined vs. total length!

Body Length

First of all, you should know that actual lengths rarely correspond to “sales” lengths! This is particularly true for travel trailers. The sales length, or the length indicated on a floorplan name, is often the nominal size of the RV body only.

More often than not, a “24-ft travel trailer” only has a body length of 24 feet. The body length is the front-to-back measurement of the box that sits on the trailer frame.

Total Length

The total length of the RV is the actual tip-to-tail measurement, body and frame included.

In the case of a travel trailer, the total length of the RV, once the frame is added, is usually about 3-5 feet longer.

Combined Length

The combined length includes the total length of the RV and the total length of the tow vehicle.

For instance, say a trailer has a total length of 26 ft. When towed with a 16-ft pickup truck, the two have a combined length of 26+16 = 42 feet.

Or if you drive a motorhome with a toad, the combined length includes both.

Do not assume whether a length restriction applies to total RV or combined length!

For instance, most campgrounds restrict total length . If you can unhitch your towable RV and move your tow vehicle out of the way, more power to you.

*This isn’t true for every campground. Some campsites have no separate parking area. In this case, the combined length is the most restrictive.

For details on how manufacturers will measure your RV, visit this page from RVIA.

How to Measure Different RVs?

Many different vehicles fit under the RV umbrella. The biggest division within these vehicles is:

• A) Whether or not you will need an extra vehicle to tow it.
• B) What type of hitch is required to tow or haul.

If we split up RV types by how they are measured, we have four types: Motorhomes, towables, 5th wheels, and truck campers. These are all measured differently.

How Do I Measure the Length of My RV?

Measuring an older rv.

it is a good idea to bring a measuring tape when you go to the retailer or do some research on your own as some manufacturer numbers are more a way to sort the different sizes than exact measurements.

For instance, the Puma 23-RBFQ model is listed as 23 feet long. In reality, it is 28 feet. Five feet can easily decide whether or not your RV will be accepted into a campground, and you do not want to find this out when you pull in after a long day of driving!

The manufacturer may provide measurements, but you should confirm with a measuring tape.

Hint: Nothing makes the job easier than an open reel measuring tape!

Some will recommend adding a few feet, just to make sure you’re covered. This may be helpful if you are new to driving an RV, but in general go with the stated/ measured number and then talk with someone ahead of time to determine any potential issues.

Measuring a New RV?

If you’re buying a new RV, you’re in luck! As of January 1, 2021, all RVIA-approved Recreational Vehicles are required to have a sticker adjacent to the Cargo Capacity label that states: “Recreational vehicle overall length ­­­­______ as manufactured.”

Thie measurement is generally extremity to extremity but does not include ladders, handles, accessory receivers, spare tires, etc.

RV Motorhome

Motorhomes offer the all-in-one option and therefore range greatly in size. Smaller class B and C motorhomes are often similar to driving an SUV (going down to 18 ft) with popular sizes ranging 20-28 ft. Large class As can feel like a semi-truck at 25 to nearly 45 ft. Remember part of that space is taken up by the actual driving area (driver’s seat, steering wheel, dashboard, passenger seat, etc.).

Towable Trailers

Towable trailers are your best bet if you’re looking for something smaller that could be towed by an SUV or mid-size truck, with options ranging from 12-40 ft. Towable trailers include travel trailers, fiberglass campers, pop-up campers, and (almost) everything in between!

How to Measure a Motorhome?

Motorhomes are the easiest RV to measure! Simply measure from tip to tail, from the front bumper to the rear bumper. This is the same for Class A, Class B, or Class C motorhomes. This length should be stated on the vehicle specifications as well.

How to Measure a Travel Trailer?

Towable trailer lengths are a common source of confusion. RV manufacturers may market the size of the RV by its interior length, exterior body length, or tip to tail length!

What you care about is total length, including the chassis frame. Measure from the tip of the trailer coupler to the rear bumper. For newer RVs, this length should be on a unit sticker as well.

Fifth Wheels are typically big, coming in sizes ranging from 25-45 feet, which allows for full-time living including bedrooms, and potentially washers, dryers, and dishwashers. They will also need a powerful truck to tow them, but are typically considered better than TTs in towability.

Truck Campers

Truck campers are sold as either slide-in or flatbed models, with the first being far more popular. They can also be hardshell or expandable. They come as small as a bed cover to a miniature mansion!

How to Measure a 5th Wheel?

When measuring a 5th wheel, measure from the tip of the overhanging nose to the rear bumper. This is the total length (imagine a hollow box the camper could fit inside of). Measuring directly off the nose could be a challenge, so it’s easier to project the nose on the ground and then measure from there. For newer RVs, this length should be on a unit sticker as well.

How to Measure a Truck Camper?

You’ll rarely have a length problem with a truck camper. But if you do need to measure one, measure from the front bumper of the tow vehicle to the rear bumper of the camper.  If you’re just looking for the tip-to-tail length of the camper itself,  you can find that on the VIN sticker.

FAQs about RVs in NPS Campgrounds

National park length limitations at-a-glance.

While the restrictions vary from park to park, the average maximum length permitted is 27 feet with about half having at least one campground allowing RVs up to 40ft.

In general, RVs between 25 and 30 feet are recommended to maximize your options as over 90% of parks permit 25 footers and 84% permit 29 footers.

IMPORTANT TIP: Most parks count the COMBINED length of your RV and your tow vehicle in their restrictions. This also applies if you are towing a car behind a motorhome.

Always call/ contact the park ahead of time to confirm these details and discuss any areas of potential concern.

Why Are NPS Campsites Small?

Many NPS campgrounds hail from the ’30s through the ’50s, when RVs were much smaller. These campgrounds can trace their heritage to the Civilian Conservation Corps or the construction and travel boom following World War II. This was the era of Scotties, Shastas and “canned hams.”

Today, the average length of a towable RV is 27-28 feet and creeping upwards. 

Finding the balance of what you need and want with restrictions and road conditions is vital to a good trip.

What are Common Park Road Conditions?

Most trafficked roads in National Parks are paved. Campground loop roads, however, are usually maintained gravel or dirt.

All bets are off when it come to backcountry sites. Access roads maybe paved, soft road, or high-clearance required. There may not even be a dedicated campground loop road!

Call ahead to confirm any road conditions after inclement weather events. Or find information about temporary road closures at the park website at the National Park Service.

Do National Parks Offer Full Hook-Ups?

Most national parks do not offer full-hookups (water, sewer, electric). Electric-only or water+electric are far more common. Dump stations are typically shared by an entire campground (or even entire park). Smaller parks may have no dump station at all.

The following national parks all offer full hookups:

• Arizona | Grand Canyon National Park: Trailer Village
• California | Death Valley National Park
• Mesa Verde National Park | Morefield Campground
• Texas | Big Bend National Park: Rio Grande Village RV Park
• Wyoming | Yellowstone National Park: Fishing Bridge RV Park
• Wyoming | Grand Teton National Park: Colter Bay RV Park

Several other campgrounds, such as the Everglades, Badlands and Gulf Islands, offer partial (electric and water only) hookups.

Do National Parks Offer Pull-Through Sites?

Unfortunately, I recommend you become an expert in backing in before reserving a spot at a National Park! Back-on sites are par for the course. Bring a set of walkie-talkies and maybe even a rearview camera.

Will National Parks Measure My RV?

Generally, no, no one will pull out a tape or stick and measure your RV. However, if your rig is obviously larger than what’s allowed, you may be asked to leave. That’s for your safety and the safety of everyone around you.

Do I Need to Reserve My NPS Campsite?

Booking a spot in a campground is highly recommended.

Many of the national parks offer multiple campgrounds with a range of maximum RV lengths, but spots fill up. Especially if you have a larger vehicle, it is best to book a spot early as those campgrounds may have a limited number of those spots available.

No matter what size your RV is, it’s best to check ahead of time which campground will work for you and reserve a spot early.

NPS reservations are first-come, first-served or reserved through ReserveAmerica.com. Some campgrounds have walk-in only sites; some don’t. Visit ReserveAmerica.com to check availability, pricing, location and restrictions.

Where Can I Find Easy References for All the Parks?

You can use the National Park Service’s Park Finder Website to sort and filter different options and then book your spots.

There are also a number of online resources that have compiled easy guides for the most popular parks. The Roving Foleys compiled an entire list of RV length restrictions by campground. You can check it out here  at TheRovingFoleys.com

Considering all of these questions before you even go to your first RV retailer will ensure that you are best equipped to make the best decision for your trip.

What Else Should I Know About the Campgrounds that Allow Bigger Rigs?

• The campgrounds that do accommodate bigger rigs typically have a smaller number of spots available.
• There may also be an upcharge for these premium spots.
• You may be able to get to the campground, but travelling to other sites in the Park may be restricted to only smaller vehicles.
• Planning ahead of time is always important with RVs and more so the bigger you go.

What About Road Access to the Parks?

Longer RV Pros

• More lounge room
• More cargo and storage
• You can escape from the kids

Longer RV Cons

• Difficult to drive and park
• Not allowed through many tunnels or mountain roads
• Prone to sway from crosswinds

What About High-Clearance Roads?

Driving a big rig is always going to be a concern if you are off-roading. This can even include general roads within a park which are often narrow, unpaved, and/or on an incline. Do your research on what type of terrain is expected both arriving and departing the campsite as well as the general area.

Many parks allow bigger rigs in their designated campsites, but other roads within the park may have length restrictions, which will restrict where you can go with your RV.

Utilizing a TT or a 5th Wheel would give you the opportunity to leave the RV at the campsite and explore in your tow vehicle.

What About U-Turns and Sharp Bends?

While some of these roads may be tight, if the campground can accommodate a vehicle of your size, your vehicle should be able to make the turns to get into the site as long as you follow the routes to the campsite and keep an eye out for roads that would prohibit a rig of your size.

What About Maximum Height?

You won’t typically find overpasses and bridges in a National Park, but you’ll often come across low-hanging trees, rock arches and natural features. Read about road conditions and restrictions beforehand.

In the Zion-Mt. Carmel tunnel, for instance, any vehicle that is 7 feet 10 inches (2.4 meters) in width and/or 11 feet 4 inches (3.4 meters) in height or larger is required to have a tunnel permit and may only pass through the tunnel during restricted hours.

What About Arrival and Departure Angles?

RVs with excessive overhangs and/or short wheelbases (here’s looking at you, Class A and Super C motorhomes) may struggle with steep inclines.

Low-riding RVs can easily get stuck or high-centered on steep or unmaintained roads. You might need to invest in larger tires, a lift kit, or an axle flip to increase your ride height (but don’t make your rig too tall!).

In general, plan ahead and do your research. Know the capabilities of your RV. Practice with it ahead of time if possible. Feel free to reach out to the Park ahead of time and ask questions about the routes into and out of the campsite/ park to help spot any potential areas to avoid.

Best RV Size for Fitting Into National Park Campsites.

By Mark on July 25, 2021

In this article, you will learn what are the best RV size for fitting into National Parks in the US.

Where do you escape for a weekend between the busy work schedule? All cities offer almost the same leisure that probably is already available in your city. The best option then is to go to the national parks and enjoy a weekend with family surrounded by nature and free from polluted air. As the national parks don’t have buildings and lodges to stay in, people must depend on staying in tents, trailers, or recreational vehicles. All the national parks have specific spots for camping and parking recreational vehicles (RVs) and trailers.

RVs are good to have and comfortable to stay in. They offer comfort, space, and security. But many people find that the RVs they purchase cannot be parked at many of the national park sites. One needs to consider this before buying an RV.

A case study shows that the optimal RV length for camping in national parks is 35′ or less. With this size, you can always find a spot to handle your rig in most parks. Hence it can be safely concluded that the ideal length for an RV should be 35 feet this can be taken as the broad guideline while purchasing an RV.

Best RV size for traveling.

Please study the road to the place you will be visiting often. There are steep winding mountain roads where some of the big-sized RVs may not be able to go. It is better to know the conditions including low-clearance areas.

Suddenly finding yourself at a place where you cannot proceed further and a compulsion to take a U-turn is unpleasant.

Most of the narrow mountain roads are not suitable to take U-turns with big-sized rigs. There are travel guides which can give you information about most of the routes to the national parks.

A case study shows that the best RV size for traveling is between 25′ and 30′.

Different national parks have campsites that have parking spaces of different sizes. So, it is imperative to know the size of the parking lot and the size of your RV.

It is wise to measure the vehicle yourself and not depend on the specification given by the manufacturer. You should measure the length, width, and height of the RV including the slide-outs.

If you are using a fifth wheel, you need to measure the total along with the tow vehicle. A longer RV may give a lot more comfortable. But one doesn’t want to find out that they can’t park their vehicles on the spot they are visiting.

Please check the weight of the RV if you are buying a trailer or a fifth wheel.

You need to know whether the pick-up or car which you use for towing will be able to take the load. If you are buying a motorhome this issue won’t arise.

But if you plan to tow a car for driving around then you should know the towing capacity of the motorhome.

Height may not be a big issue in most places. But there are roads with low-clearance areas. It is better to know this beforehand so that you don’t find that you have to take a different route.

Though other dimensions are important to an extent, it is the length of the vehicle that is the crucial factor to consider when buying an RV.

What Are the Best RV Lengths for National Parks?

All of the following numbers from the list are COMBINED lengths of the tow vehicle and the trailer so you need to add the length of the RV and the vehicle together.

Here are the averages lengths:  RVs up to 12′  fit in all national parks, from 19′ to 25′ in length fit in 91%, from 25′ to 32′in length fit in77%, from 32′ to 37′ in length fit in 58% and RVs up to 40′ in length fit in 50% of all national parks in the US.

To make things easier I decided to study the size restrictions of the most popular national parks in the country.

RV Size Limits for Most Popular National Parks

Most sites in the Yellowstone national park permitted a size of 40 feet for RVs.

• Fishing Bridge RV Park – Up to 40′ RVs
• Canyon Village Campground – 40′ COMBINED RV length
• Bridge Bay Campground – 40′ COMBINED RV length
• Madison Campground – 40′ COMBINED RV length
• Grant Village Campground – 40′ COMBINED

At the Joshua Tree national park certain campgrounds had a very small allowance of 25 feet. But most other sites could accommodate an RV of size not exceeding 35 feet.

• Black Rock Campground – Half of the sites take in up to 25′ in combined length, and half go up to 35′.
• Hidden Valley Campground – The COMBINED length of RV and towed vehicle or toad is only 25′
• White Tank Campground  – The COMBINED length of RV and towed vehicle or toad is only 25′

In the Yosemite Valley 12 sites – six each in Lower Pines and North Pines can take RVs up to 40 feet long. But there are many more sites that can take the size of only up to 35 feet.

At the Redwoods National and State Parks, California the size at the various sites ranges from a maximum of 36 feet to a minimum of 24 feet.

• Jedediah Smith Campground – Trailers 31′
• Mill Creek – Trailers 27′
• Elk Prairie – Trailers 24′,
• Gold Bluffs – Trailers PROHIBITED, motorhomes 24′

At the  Great Smoky Mountains, the size of the various sites ranges from 12′ to 35′ for trailers. 

• Abrams Creek – 12′
• Balsam Mountain – 30′
• Cade’s Cove – Trailers up to 35′ and Motorhomes up to 40′
• Cataloochee – 31′
• Cosby – 25′
• Deep Creek – 26′
• Elkmont – Trailers 32′, motorhomes 35′
• Look Rock – No limit
• Smokemont – Trailers 35′, motorhomes 40′

At Arcadia National Park 

• Blackwoods Campground – 35′ in COMBINED length of the tow vehicle (or towed vehicle) and the RV itself.
• Seawall Campground – 35′ in COMBINED length of the tow vehicle (or towed vehicle) and the RV itself.

At Arches National Park

• Devil’s Garden Campground – 25% of the spots accommodate an RV and towed vehicle combined length of 25′.  25% of the spots take an RV up to 30′, and 25% of the spots can fit an RV up to 40′.
• Archview Campground – Up to 50′ in length, but you have to pay more for these premium spots.
• Moab Valley Campground – Up to 44′ in length, but you have to pay more for these premium spots.

Conclusion:

I wish everyone happy camping and a great time with families.

Related Questions:

The size of the RV is one of the most important factors when it comes to fitting into National Park campsites. Not all of these have campgrounds that will be suitable for your RV. It’s important to know what size park your RV will be able to fit into. Make sure that you’re familiar with the campground restrictions of each National Park beforehand, so you are not caught unawares when traveling through them. Here are most of the questions Rvers ask.

What size RV is allowed in Yellowstone?

Many travelers have been denied entry into this national park for driving non-compliant RVs. What does non-complaint RV mean? It’s an RV with a length longer than 21feet and 8inches or width more than 8feet and 6inches, hence not be allowed to enter.

What is the best length RV for state parks?

RVing offers a lot of freedom. It is the ultimate in nomad-like living! Not all parks and campgrounds have long enough electrical and sewer connections for larger RVs. If you are looking to buy an RV, a 30′ class C might be the perfect size to give you everything that you want without being too big to fit into smaller campgrounds or parks with limited space.

What is the average size of an RV campsite?

The average size of an RV campsite is 30 feet by 50 feet. The typical campsite measures about 28 feet wide, 50 feet deep, and 8 to 9 feet between the front side of one side and the backside of the next.

What is the best size RV to buy?

There are trailers as small as 20 feet long and 5 feet wide, and there are motorhomes that are as long as 45 feet. A good starting point is to decide how many people you can have slept in the RV at one time and if you have a pet or two.

Don’t be pressured into buying an RV that’s just a little bit too big. The fancier an RV is, the higher the price tag will be. It’s better to buy an RV that has fewer extra features and lower monthly payments.

Boondocking is when the RV parks for free at a destination called boondocking spot. Boondocking itself isn’t illegal; legal requirements vary from state to state or province to province.

Is a 40-foot motorhome too big?

Some people would consider a 40-foot motorhome to be the perfect size for long-term travel as it has all the amenities you need and it’s also small enough to move around. However, there are people who consider a 40’ to be too big and would prefer one that is smaller because they miss out on many opportunities for adventure and it is harder to get into campgrounds at most parks.

Can you drive an RV through Arches National Park?

Yes, according to the park service’s website “all vehicles including RVs are allowed on all roads unless specifically posted otherwise.” However, they would prefer if visitors didn’t.

What RV Size Is Best for National Park Campsites?

The best of anything is usually a matter of opinion. The best RV size for national park campgrounds, however, is not. That’s because, while a large RV provides a spacious and comfortable place to stay, many buyers of very large RVs regret their purchase when it comes to finding a campsite. If your RV is too long, state and national parks are notoriously difficult to camp in.

I’m currently looking for a Class A RV. So I decided to look into the best RV size for national park campgrounds across the country. Here are the results of my research.

Is Length Important? Is there an optimum RV size for national park camping?

After much research, I believe that the best RV size for national park campsites is 35′ or less. At that size, almost any national park in the country will have a spot large enough to accommodate your rig.

The lengths listed below are the COMBINED lengths of the tow vehicle and the trailer/fifth wheel, or of the motorhome and the towed vehicle. As a result, you must add the length of the RV and the vehicle together.

• Keep in mind that RV manufacturers frequently inflate the length of their vehicles. Take out a tape measure and measure your RV to find out—probably it’s longer than the manufacturer advertised.

The Best Length for a Travel Trailer (Size Chart Included)

NOTE*** The content on this page may contain affiliate links, we  may make a commission. And, as an Amazon Associate, we earn from qualifying purchases.   More information:  disclosure page .

Just in the last decade, I have owned, rented, and sold a number of travel trailers. I have my own share of experience with the different lengths and sizes of RVs. In this article, we get into the different travel trailer sizes and include a travel trailer size chart for you.

What size travel trailer should you buy?

Generally speaking, the ideal travel trailer length for a family of 4 is 25-30 feet long. With a 27-foot travel trailer, you can likely park in your driveway, camp at 93% of national parks, and still have room to sleep 4-6 people comfortably.

Generally, for convenience, longer travel trailers are the best choices for a family with at least 4 members or more. However, there are roads and campsites that have limits on the lengths that they can accommodate.

I have personally experienced the benefits and drawbacks of traveling in different lengths of trailers. So I made this article in the hopes of helping you determine which is the best length for a travel trailer for you. It can also serve as a guide so you can rule out the other sizes that you know won’t work for you.

No matter how long your trailer is you need to see behind you. Campsites can be tight and have obstacles (like kids). A  wireless backup camera  makes life so much easier .. and safer. This wireless camera on Amazon is easy to install, budget-friendly, and best for shorter trailers ( check price here )

Longer trailers and especially with metal siding will need a wired backup camera. This takes a little longer to install but you can still do it yourself. We suggest this  wired backup camera on Amazon .

Best Size Travel Trailer by Length

Some will say that anything above 30 feet is too long for a travel trailer. But the truth is that the answer to whether a travel trailer is too long lies on your tow vehicle.

As a rule of thumb, the longest trailer that your tow vehicle can pull is the one that does not exceed 75% of the maximum loaded weight of your vehicle.

Travel Trailer Size Chart

I put together this travel trailer size chart to help you see the length, weight, and accommodations for travel trailers. This is based on reviewing hundreds of RVs and my own experience.

A big consideration is the number of people in your family. How long does it have to be for you and your family to live in it comfortably?

Travel Trailer Length Based on Camping Preference

Some people report that a travel trailer that is more than 35 feet is a problem when they are looking for a campground to set up base on. Many of the available campgrounds, especially national parks, only have limited and small space.

However, if you own a bigger rig, finding the right campground is possible if you are willing to stay in the vicinity of the sites.

The question will lie in your preferences. Do you plan to camp in National Forests or dispersed campgrounds? If so, then having a long rig will seldom be a problem for you as these campgrounds usually can accommodate longer rigs.

If you prefer to camp in National Parks or small private campgrounds then this might prove to be a slight problem as these campgrounds usually have limits on how long of a rig they can serve.

Pro Tip: Make sure to look into the campgrounds that you plan to stay at. When you are thinking about tight spaces or bumpy roads take into account eh turning radius and hinge point of the trailer.

How to Measure the Length of the Travel Trailer

The length of the travel trailer that your manufacturer specified is the box of the trailer and considered your trailer length. State-run campgrounds and some private ones usually base their site length upon the length of the travel unit itself.

Most often than not, there will be a separate parking space for your tow vehicle.

I own a 35-feet travel trailer. It is specified by the manufacturer as 35-feet. When I call to reserve a campsite, I ask for 35 feet or longer.

However, when going through roads that have length restrictions, you have to make sure to measure the whole length with your tow vehicle.

For example, in Independence Pass near Aspen, Colorado, RVs more than 35 feet in length are prohibited to pass. We have a 35 feet trailer but our total length from the bumper from the front of the truck to the bumper at the back of the trailer is 59 feet. (We know this because we were measured when we took the ferry from Seattle. )

Does Travel Trailer Length Include the Tongue and Hitch?

The trailer length and the manufacture description do not include the tongue and the hitch. The length is only the inside box of the trailer.

If you want to know exactly how long your trailer will be you need to include The rear bumper, any accessories like a bike rack, and the front tongue and hitch. The rear bumper generally adds 6 to 12 inches. The front tongue and hitch add 2 to 3 feet to the length.

So for example my 35-foot travel trailer is 38 feet bumper to hitch. It’s even longer when the  bike rack is on the back . When towing it with a truck it is 59 feet bumper-to-bumper.

How Does Length of the Trailer Affect Towing

A longer trailer will move differently behind the truck than a shorter trailer. Both the length and weight of the trailer affect the amount of weight on the tongue and swaying the backend. Most experts agree that a longer trailer is actually easier to tow because it will have a slower delay.

Weight distribution and sway bar will help you tow a trailer. This is the set that I use which is easily installed and works great.  Check the price on Amazon.

However, the total radius with a longer trailer will be longer. Therefore your turns will be much wider. In addition, you only to watch the inside corner very carefully for obstacles.

What Are the Disadvantages of a Longer Trailer?

The longer your trailer is, the more difficult it is to look for camps to stay in. Generally, state parks commonly have a length restriction of 35 to 45 feet. However, when your rig is 41 feet or above, you have to expect that you will only be accommodated by less than 10% of the campsites. On the other hand, 98% of campsites can accommodate trailers that are 19 feet and less.

Another disadvantage of a longer travel trailer is the total weight. Once you get up to 30 or more feet and 7 to 8,000 pounds you will need a 3/4 ton or 1-ton truck to tow it.

Pro Tip: Keep in mind that you’re towing capacity will be reduced by up to 20% at altitude and over the mountain passes 

A longer trailer has more tail drag in the back end. You will need to be driving on relatively flat roads.  So you will be limited to maintained roads and campgrounds.  You will not be able to off-road or boondock much.

What are the Advantages of a Longer Travel Trailer

A bigger, longer-length travel trailer has many advantages.  A longer camper has more room inside giving you more space to move around.  You will also have more privacy.  My trailer with 35 feet length actually has 2 separate bedrooms with doors.

Another advantage is the convenience of the space.  A smaller camper will need to be spending time changing the inside back-and-forth between living quarters and sleeping quarters. Our first Trailer was a 20-foot long vintage camper with no slide-outs. Every night and every morning we had to transform it back into a table put the bunks away and make the bed back into a couch just to have breakfast.

A longer travel trailer can carry more weight. Once you have a camper you will want to load it up with all your favorite camping gear. You would be surprised how much your toys end up weighing.

In addition, if you are Boondocking he will be also be carrying a full tank of water to your campsite.

A larger trailer also responds to movement when towing more slowly than a short trailer. Some people even say driving a longer trailer is easier than a shorter one. The hinge point at the back of the tow vehicle and the distance to the back end of the trailer is longer. The physics determines how quickly the very back of the trailer responds to small adjustments in the front.

Overall, I never recommend buying an RV before trying out if you like it. You can see all my thoughts here:  17 Undeniable Reasons Why You Should NOT Buy an RV

Summing up the Ideal Length of a Travel Trailer

The best length for your travel trailer will depend on the needs of your family. If you are traveling long-term and want more space and amenities similar to an apartment, you will require a bigger camper. If you are planning on shorter trips to national parks and sightseeing, a shorter travel trailer will likely work for you.

Before buying a camper I always suggest that you try renting at least one similar to what you’re thinking of buying. Travel trailers are difficult to rent from national companies. However, you can rent from a private owner on  Outdoorsy  or  RVezy .

To rent a camper similar to the one you’re thinking of buying simply go to the  Outdoorsy  or  RVezy  website. Once you’re on the website choose the destinations that you would like to pick up the travel trailer. Then from the options choose the number of people that should sleep and your ideal length.
