Will It Tow?
2025 Ram 3500 (6.7L Cummins I6 turbo diesel) with the 2027 Forest River Rockwood Signature Fifth Wheel R371RK at its full GVWR of 12,401 lb, two adults and a dog aboard and a weight-distribution hitch.
Closest: payload, at 99% of its limit. Pack light and weigh it when you can.
- Tow rating: 11,149 lb to spare (12,401 lb camper, rating 23,550 to 26,080 lb)
- Payload: 50 lb to spare (3,052 to 3,920 lb used, payload 3,970 to 4,400 lb)
- Truck and trailer together: Not sure yet (at least 20,680 lb, GCWR 31,820 to 34,000 lb)
To settle it for your own truck: measure your pin weight.
Check it with your own numbers- Fifth wheel hitch (needed): Rated for at least your camper's weight (12,401 lb) and about 3,200 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 2,232 to 3,100 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.
