Will It Tow?
2027 GMC Sierra EV (Dual-motor electric) with the 2027 Forest River Vibe 3400SB at its full GVWR of 11,475 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: Not sure yet (11,475 lb camper, rating 8,500 to 12,500 lb)
- Payload: Not sure yet (2,087 to 2,431 lb used, payload ? lb)
- Truck and trailer together: Not sure yet (, GCWR not listed)
To settle it for your own truck: enter the payload from your door sticker (the yellow Tire and Loading one); enter your exact tow rating from your owner's manual or the maker's towing chart; 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 40 ft, your camper catches a lot of wind. Many weight-distribution hitches have it built in.
- Spring bars rated about 1,400 to 2,100 lb (size): Match the bars to your loaded tongue weight (1,377 to 1,721 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 1,377 to 1,721 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.
