Is there such a thing as an average travel trailer length? Mathematically speaking, yes, it’s about 30 feet. But you can always average out numbers, so let’s do some checking into why travel trailer length might matter to you.

Susan and I are considering buying a travel trailer and we were discussing how long it should be. We want it to be big enough for us to live in comfortably, yet small enough to tow easily. We also want to make sure it fits into most campsites. But the number one thing we kept coming back to was the length of the travel trailer.

Of course, we will go through Outdoorsy to find our travel trailer rental. They have a great platform that makes renting an RV easy and hassle free.


PRO TIP: One thing we know for sure is that we will rent a travel trailer before we decide which one to buy. Even though we are experienced RVers we don’t currently have a travel trailer so we plan to rent one, or more, to help determine which length and style of travel trailer will work best for us.

Is There a Maximum Travel Trailer Length?

The maximum allowable travel trailer length is determined by each state. I took a look at the lengths allowed in states throughout the USA and averaged out the travel trailer length as a whole. The number I came up with was 41 feet – sounds like a large travel trailer, right? Let’s look at a few state-by-state numbers, however, as examples. Please note, “total length” means the length of your travel trailer and vehicle combined.

  • Alabama: Total length: 57 feet – Travel trailer: 28 feet, 6 inches
  • Colorado: Total length: 75 feet – Travel trailer: 45 feet
  • Florida: Total length: 65 feet – Travel trailer: 48 feet
  • Iowa: Total length: 65 feet – Travel trailer: 45 feet
  • Louisiana: Total length: 65 feet – Travel trailer: 30 feet
  • New Mexico: Total length: 65 feet – Travel trailer: 40 feet
  • Texas: Total length: 65 feet – Travel trailer: 28 feet, 6 inches
  • Wisconsin: Total length: 70 feet – Travel trailer: 48 feet

average travel trailer total length

Since many RVers travel throughout the United States, it leads one to believe that states tend to not be overly strict with the length of RVs. How could they be if you are traveling with your 35-foot travel trailer from Florida into Louisiana or Alabama?

The total length combination seems to be a more reasonable length to adhere to for obvious safety reasons while making one’s way across the USA. However, keep in mind that each state does have specifications regarding tow vehicle and motor home lengths.

Several websites discuss state requirements and laws. One such site you can use as a good resource is RV Trip Wizard which lists length height and width for travel trailers in every state. We are an affiliate of RV Trip Wizard and love their trip planning software because you can enter the exact dimensions of your RV into the program. RV Trip Wizard will then plan your trip route so you fit everywhere you want to go!

We learned the hard way that Waze or GoogleMaps will not work to plan the best route when driving an RV. We actually got stuck at a bridge we could not drive under in rush hour traffic in the North East! Yikes! Anyway, we highly recommend RV Trip Wizard not only because you can enter the size of your RV but also because it is the BEST trip planning tool we have found. We absolutely think it is awesome and you will too. Just click on any of our RV Trip Wizard links to check it out for yourself.

Travel Trailer Sizes Best Suited for National Parks

Each National Park has its own policy regarding campground(s), amenities, and RV lengths best suited for their sites. Very few, in fact, we only found 3, provide full hookups. Many provide electric, but no water hookups and a large number of national parks offer no hookups whatsoever in their campgrounds. For those wishing to experience the campgrounds without hookups, you may have the option of using a generator during certain hours and/or filling your freshwater tank for personal use.

We found that, as an average, a length of 30 ft. is the maximum to fit into a national park campground. With that said, you’ll find a surprising number of national parks that now offer availability for 40-foot RVs. One to two parks we looked at even have accommodations for RVs 50 to 60 feet. Some campgrounds only have a few sites available for larger RVs, so it’s best to make your reservations as quickly as you can.

Camping reservations are generally made 6 months in advance of your arrival at www.recreation.gov. To be assured you reserve the appropriate campsite you need, sign up with a login and password ahead of time at the recreation.gov site. Then double check what amenities are provided, the allowable trailer length on the particular campsite (s) you are interested in, if the campground is pet-friendly, and how far in advance you can make a reservation. A few national parks allow reservations more than six months in advance. Many parks can book up quickly, depending on location and time of year.

Some national park campgrounds are contracted out to concessionaires to manage. The recreation.gov site will alert you if this is the case and direct you to the appropriate website so that you can make your camping reservation.

As an added note, remember that most state parks also adhere to sites that can accommodate only RVs of particular lengths. State parks tend to offer sites with electricity and water at a minimum and do provide dump stations. Be sure to check each state park’s amenities and allowable lengths before reserving.

Measuring the Length and Height of Your Travel Trailer

Travel trailers and RVs, in general, can have a few length and height criteria depending on why you need the measurement. The interior length, width, and height is your actual living space. The width, therefore, would be measured with all slides extended to include actual living space.

The exterior length and height are helpful to know for several reasons. Perhaps you need to pay a toll, which requires you to travel through the toll booth. You may have covered bridges along your route or small bridges that cross a river or creek. You’ll also need a total length for fitting into campsites or storing your RV.

The exterior width can be measured with the slide in, giving you the width for traveling particular roads or bridge crossings, as well as a measurement with the slide out, which will be beneficial when making campground reservations.

For safety’s sake, measure the height of your RV once it is hooked up to the tow vehicle. Be sure to include any vents, air conditioning units, or even antennas that extend up from the roofline. This assures you complete confidence in making it past any drive throughs, toll booths, bridges, tunnels, and the like.

The exterior length of your travel trailer will always be longer than the interior. The exterior length will be the overall length, including the tongue and bumper. It’s also a good idea to take a total length measurement of the trailer and vehicle once you are hitched up and ready to roll.

Keep these measurements either in the glove compartment of the tow vehicle or an easily accessible place inside your travel trailer. They can come in handy when you least expect it.

As you see, the answer for what an average length travel trailer is may not be quite as simple as it sounds, but rest assured once you find your “average,” it will be just the right answer for you.
