Will It Tow?
2027 GMC Sierra EV (Dual-motor electric) with the 2027 Forest River Rockwood Signature Fifth Wheel R372RL at its full GVWR of 12,305 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: Not sure yet (12,305 lb camper, rating 8,500 to 12,500 lb)
- Payload: Not sure yet (3,035 to 3,896 lb used, payload ? lb)
- Truck and trailer together: Not sure yet (, GCWR not listed)
To settle it for your own truck: enter the payload from your door sticker (the yellow Tire and Loading one); enter your exact tow rating from your owner's manual or the maker's towing chart; measure your pin weight.
Check it with your own numbers- Fifth wheel hitch (needed): Rated for at least your camper's weight (12,305 lb) and about 3,100 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.
- 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 2,215 to 3,076 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.
