Will It Tow?
2026 Ram 3500 (6.7L Cummins I6 turbo diesel) with the 2027 Grand Design Momentum G-Class TT 29GS at its full GVWR of 13,000 lb, two adults and a dog aboard and a weight-distribution hitch.
Closest: payload, at 70% of its limit.
- Tow rating: 10,000 lb to spare (13,000 lb camper, rating 23,000 lb)
- Payload: 1,180 lb to spare (2,270 to 2,790 lb used, payload 3,970 to 4,400 lb)
- Truck and trailer together: Not sure yet (21,480 lb, GCWR up to 34,000 lb)
Check it with your own numbers- Weight-distribution hitch (needed): Your camper is over 5,000 lb. Most truck makers require weight distribution here, and many receivers are rated far lower without it. It spreads the tongue weight to your front axle and the camper's axles, so the truck sits level and steers right.
- Sway control (strongly recommended): It stops the camper swinging side to side in crosswinds, when semis pass and on rough roads. At about 35 ft, your camper catches a lot of wind. Many weight-distribution hitches have it built in.
- Spring bars rated about 1,600 to 2,400 lb (size): Match the bars to your loaded tongue weight (1,560 to 2,080 lb, from an estimate of 12 to 16% of the camper's weight) plus anything heavy behind the truck's rear axle. Bars that are too stiff ride rough. Too light won't level the rig.
- 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 tongue weight (tip): We're estimating 1,560 to 2,080 lb. A tongue weight scale or a hitch with a built-in gauge 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.
