Will It Tow?
2026 GMC Sierra 3500HD (6.6L Duramax V8, dually) with the 2026 Coachmen Northern Spirit 2975RL at its full GVWR of 9,800 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: 10,200 lb to spare (9,800 lb camper, rating 20,000 lb)
- Payload: Not sure yet (1,886 to 2,180 lb used, payload ? lb)
- Truck and trailer together: Not sure yet (, GCWR 40,000 to 43,900 lb)
To settle it for your own truck: enter the payload from your door sticker (the yellow Tire and Loading one); measure your tongue weight.
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 36 ft, your camper catches a lot of wind. Many weight-distribution hitches have it built in.
- Spring bars rated about 1,200 to 1,800 lb (size): Match the bars to your loaded tongue weight (1,176 to 1,470 lb, from an estimate of 12 to 15% 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 1,176 to 1,470 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.
