Will It Tow?
2026 Chevrolet Silverado 3500HD (6.6L Duramax V8, dually) with the 2026 Coachmen Catalina Trail Blazer 29THS at its full GVWR of 10,578 lb, two adults and a dog aboard and a weight-distribution hitch.
Closest: tow rating, at 53% of its limit.
- Tow rating: 9,422 lb to spare (10,578 lb camper, rating 20,000 lb)
- Payload: 2,976 lb to spare (1,979 to 2,402 lb used, payload 5,378 to 6,644 lb)
- Truck and trailer together: Not sure yet (, GCWR 40,000 to 43,500 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 36 ft, your camper catches a lot of wind. Many weight-distribution hitches have it built in.
- Spring bars rated about 1,300 to 2,000 lb (size): Match the bars to your loaded tongue weight (1,269 to 1,692 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 1,269 to 1,692 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.
