As for the Hummer EV’s payload and trailering capacities, GMC claims 7500 pounds. However, other electric pickups, such as the Rivian R1T and the Ford F-150 Lightning, can tow up to 11,000 and 10,000 pounds, respectively. The Hummer EV’s range plummeted to barely 140 miles at 70 mph when we towed a 6100-pound, double-axle camping trailer.
