Will It Tow?
2020 GMC Sierra 2500HD (6.6L V8) with the 2027 Forest River Wildcat Fifth Wheel 37GALLEY at its full GVWR of 14,080 lb, two adults and a dog aboard and a weight-distribution hitch.
To know for sure, enter the payload from your door sticker (the yellow Tire and Loading one).
- Tow rating: 420 lb to spare (14,080 lb camper, rating 14,500 to 17,370 lb)
- Payload: Not sure yet (3,354 to 4,340 lb used, payload ? lb)
- Truck and trailer together: Not sure yet (21,380 lb, GCWR up to 24,000 lb)
To settle it for your own truck: enter the payload from your door sticker (the yellow Tire and Loading one); measure your pin weight.
Check it with your own numbers- Fifth wheel hitch (needed): Rated for at least your camper's weight (14,080 lb) and about 3,600 lb of pin weight. That points to a 16K-class hitch or bigger. It mounts in the bed over the rear axle.
- Weight distribution and sway control (not needed): Fifth wheels ride on a hitch over the truck's rear axle, which makes them much more stable than a bumper-pull. These are for travel trailers.
- Short bed? (check): With a bed under 8 ft, use a slider hitch or a pin box made for short beds so the camper clears your cab on tight turns.
- Brake controller (needed): Your camper has electric brakes, and the controller in your cab runs them. Many newer trucks have one built in.
- Measure your pin weight (tip): We're estimating 2,534 to 3,520 lb. A CAT scale weigh, hitched and unhitched, gives you the real number. Enter it in step 2.
Hitches make towing steadier, but none of them raise your tow rating or payload. The hitch itself counts against payload.
Ratings come from manufacturer towing guides and spec sheets. These are planning estimates, not a safety guarantee. Your truck and camper stickers, your owner's manual and a scale always win.
