Will It Tow?
2020 Ram 3500 (6.4L HEMI V8, dually) with the 2027 Jayco Eagle 321RSTS at its full GVWR of 13,200 lb, two adults and a dog aboard and a weight-distribution hitch.
Closest: tow rating, at 97% of its limit. Pack light and weigh it when you can.
- Tow rating: 460 lb to spare (13,200 lb camper, rating 13,660 to 18,210 lb)
- Payload: 2,510 lb to spare (3,196 to 4,120 lb used, payload 6,630 to 7,680 lb)
- Truck and trailer together: Not sure yet (20,660 lb, GCWR up to 25,000 lb)
Check it with your own numbers- Fifth wheel hitch (needed): Rated for at least your camper's weight (13,200 lb) and about 3,300 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 2,376 to 3,300 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.
