How Big and Long Is the Largest Travel Trailer?

You’ve probably seen some huge Class A motorhomes speed down the interstate. These units tend to max out around 45 feet in length, and that’s a lot of square footage moving at 65 miles per hour. But have you ever seen a 45-foot travel trailer? Probably not. But there are travel trailers that measure over 40 feet in length. Do you want to know more about the largest travel trailer options on the market today? 

Let’s dive in!

How Long Can Travel Trailers Be?

Travel trailers, also called bumper pulls, are the most common type of RV. A vehicle with a ball and hitch tows them. These trailers can be anywhere from 10 feet to 40+ feet long!

Your state DOT generally limits how big your RV travel trailer can legally be.

  • Most states generally restrict RV travel trailer length to 40 feet
  • Some states allow for a couple of additional feet, with a maximum of 43′ 6″. This doesn’t include the tow vehicle.
  • In most states, the maximum combined length is usually between 50 feet to 65 feet.

Look up your vehicle’s registration state on’s RV Size Limits list to find out your limit.

Because there are various subtypes of travel trailers, like pop-ups, teardrops, and standard travel trailers, their lengths vary tremendously. Generally, most standard travel trailers are under 35 feet long.

How Big Are The Largest Travel Trailers?

The longest travel trailer used to be the Jayco 340DROK, but it’s no longer in production. It had a GVWR of 12,825 pounds, which means you’d need at least a three-quarter-ton truck to tow it safely. The dry hitch weight was 1,480 pounds. This is the amount of weight put on the ball of the tow vehicle. 

The current longest travel trailer is the Jayco 38BHDS which is 40’6″ long. Take a closer look at the three of the largest travel trailers currently in production.

#1. Jayco Flight 38BHDS

  • Length: 40 feet 6 inches
  • GVWR of 10,750 pounds
  • Cargo carrying capacity of 2,600 pounds
  • Dry hitch weight of 1,045 pounds.

The Jayco Flight 38BHDS is a unique travel trailer floorplan with two separate bedrooms, one in the rear and one in the front. Both feature queen beds with closet storage. However, there’s also the option to change out the front bedroom for a bunk room and the rear queen bed for a king bed. 

The split bathroom is similar to what you find in a motorhome, with the shower on one side of the hall and the sink and toilet on the other. A jack-knife sofa and U-shaped dinette complete the living space.

#2. Cherokee 324TS

  • Length: 40 feet 5 inches
  • GVWR of 11,365 pounds
  • Hitch weight of 1,165 pounds
  • Cargo-carrying capacity of 2,762 pounds.

The Cherokee 324TS requires a heavy-duty truck to tow it. The floorplan features a rear bunk room with a cube sofa, a U-shaped dinette and sofa in the living space with an entertainment center and electric fireplace, and a front bedroom with a queen bed. There’s an outdoor TV mount as well as an outdoor kitchen.

#3. Jayco Eagle 30RSTS and 332CBOK

  • Length: 40’1”
  • GVWR of over 10,600 pounds

The 30RSTS sleeps up to six, while the 332CBOK sleeps up to four. The 30RSTS has an extra pull-out sofa in the living space. 

Both of these models feature a kitchen island, an entertainment center with an electric fireplace, a king bed in the primary bedroom, a 21-cubic-foot residential refrigerator, and washer and dryer hook-ups in the bedroom wardrobe. These floor plans are very similar to fifth-wheel floorplans.

Honorable Mention: KZ Sportsmen Destination 364BH

  • Length: 41’2″
  • GVWR of 10,460 pounds
  • dry hitch weight of 1,810 pounds
  • Cargo carrying capacity is more limited at 1,060 pounds

Although this model by KZ is considered a “destination trailer,” it looks more similar to a standard travel trailer than most destination trailers.

Uniquely designed, this model features a rear primary bedroom with a king bed and a bunk room in the unit’s center. The large front living space features a tri-fold spade and theater seating, a free-standing dinette, and a peninsula countertop in the kitchen.

Pros and Cons of Bigger Travel Trailers


  1. Amount of living space. The longer the trailer, the more interior space. This means more room for the kids’ toys, working remotely, and entertaining. 
  2. There can be a separate room. This can be very helpful for older teenagers or a separate office space for travelers who have to work while traveling. Even though it’s still a small space compared to a sticks-and-bricks house, there is more space for privacy among family members.


  1. Heavier. This can strain vehicles that are maxed out on towing capacity and make it dangerous to drive for both you and others on the road.
  2. Requires Larger Tow Vehicle. Owners usually have to invest in a larger tow vehicle, which means more out-of-pocket money spent.
  3. Size limitations at various campgrounds. Some locations don’t permit RVs over 40 feet in length because the campsites aren’t large enough. National park campgrounds have even smaller sites, so the chances of getting into Watchman Campground in Zion or Bass Harbor Campground in Acadia are very slim.
  4. More difficult to tow. Sway increases the longer the trailer, which means less control in windy conditions. Even with a heavy-duty truck, you can still feel the pull as a semi-truck passes by on the interstate.
  5. Turning is more difficult with a longer rig. Driving along backcountry roads or through city streets can be much more stressful.

While large travel trailers offer more space, they also make it harder to find campsites you can fit into.

Is the Largest Travel Trailer Worth It?

If you have a large family and need the space to keep fights to a minimum and accommodate sleeping arrangements, then the biggest travel trailer may be a good fit. But if you don’t need the added space, it’s more convenient to purchase something smaller. You’ll have more options for overnight stays and less stress while towing.

I'm a bumper pull guy and I read your "Largest Travel Trailer" article with interest. Your pro/con points were right on. An additional pro/con is a 5th wheel comparison. For me the 5th wheel advantage is: more storage capacity, 5th wheel hitch over rear axle, more floor plans. Trailer advantage: not as tall (I drive lots of 2 lane roads), easier to hitch up, price (maybe?)

I enjoy your blog....Lee Meyer
