Travel Trailer or Fifth Wheel: How They Differ and Which One Fits

Federal safety rules define a recreation vehicle trailer as one built to be drawn by a bumper, frame or fifth wheel hitch and set up for temporary living. The two types split on that hitch:

• Travel trailer: the coupler on the trailer’s tongue drops onto a ball hitch behind the rear bumper. The hitch sits behind the truck’s rear axle.
• Fifth wheel: the raised nose of the trailer reaches over the tailgate, and a pin under it locks into a hitch mounted in the pickup bed. Go RVing says this lets the trailer pivot over the truck’s rear axle, which many owners find stable and smooth.

A fifth wheel takes a pickup with a fifth-wheel hitch installed in the bed.

A travel trailer takes anything with a hitch rated for its loaded weight. Go RVing says the smaller models can go behind a mid-size vehicle, and the larger ones need an SUV or a pickup.

With either one, part of the trailer’s loaded weight rides on the truck, and it counts against the truck’s payload. Your truck’s limit is on the Tire and Loading Information label, which NHTSA says is on the driver’s side door edge or post. How much each type typically puts on the truck, and a worked example, are in the tow guide.

• GVWR (gross vehicle weight rating): the manufacturer’s rating for the trailer’s loaded weight. Plan against this one.
• Dry weight: the brochure number. Go RVing describes it as the trailer with empty water tanks, empty propane tanks and none of your gear. Nobody tows a trailer at its dry weight.
• Cargo carrying capacity: how much you can load before you reach GVWR. Federal standard FMVSS 120 requires the manufacturer to put a yellow label stating it on every RV trailer, on the inside of the forward-most entry door on the right side. That label counts full propane tanks as part of the empty trailer and counts fresh water as cargo.
• Hitch weight and pin weight: the share of the loaded trailer that sits on the truck, on the ball for a travel trailer and in the bed for a fifth wheel. FMVSS 120 builds it in: a trailer’s axle ratings plus the manufacturer’s recommended tongue weight have to add up to at least its GVWR.

On a used trailer, find both the GVWR on the trailer’s own certification label and the yellow cargo label before you compare it to your truck.

A fifth wheel is built around its raised front section. That gives it a split-level floorplan, usually with the bedroom up front over the truck bed, and room for tall ceilings and big living areas behind it. Go RVing lists fifth wheels at roughly 21 to 40 feet, some with up to four slide-outs, with large exterior storage compartments, and a big rear window.

A travel trailer is one level, end to end, and comes in more shapes and sizes than any other RV. Go RVing lists them at roughly 20 to 35 feet, from a couple’s weekend trailer to a family bunkhouse with bunk beds for the kids and a closed bedroom for the parents.

Both unhitch and stay put, so the truck is free for errands and day trips. A travel trailer comes off the ball; a fifth wheel comes off the hitch in the bed. If you have never hitched either one, we hook it up to your truck with you on pickup day, as part of how buying an RV works here.

• A fifth wheel fits someone who already has, or plans to buy, a pickup that can carry the pin weight, and who wants room to spread out. Go RVing points to couples who want separate living and sleeping spaces, families, and travelers who stay put for weeks or a season.
• A travel trailer fits someone whose tow vehicle is not a pickup, or who wants a smaller, lighter rig, or who wants the widest choice of floorplans at every size.

Either way the paperwork is the same. In Texas both are trailers: every one on a public road is registered, and whether it needs a title goes by gross weight. The Texas title and registration guide has the rules.

Send us the year, make and trim of your tow vehicle and the floorplans you are looking at, through the tow guide, and we will look at your payload with you. Final confirmation always comes from your vehicle manufacturer and the label on your truck. Then see the travel trailers and 5th wheels on the lot.
