Will It Tow?
2025 GMC Hummer EV Pickup (Tri/dual-motor electric) with the 2027 Forest River No Boundaries NB20.7 at its full GVWR of 7,123 lb, two adults and a dog aboard and a weight-distribution hitch.
Over on payload.
- Tow rating: 377 lb to spare (7,123 lb camper, rating 7,500 to 8,500 lb)
- Payload: Over by 265 lb (1,565 to 1,778 lb used, payload up to 1,300 lb)
- Truck and trailer together: Not sure yet (, GCWR not listed)
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 29 ft, your camper catches a lot of wind. Many weight-distribution hitches have it built in.
- Spring bars rated about 900 to 1,400 lb (size): Match the bars to your loaded tongue weight (855 to 1,068 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 855 to 1,068 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.
