GMC Hummer EV Tows 30-Foot Camper Through Rockies, But Fast Charging Costs More Than Diesel

A GMC Hummer EV owner recently documented a 525-mile round-trip towing run to Colorado’s Great Sand Dunes, pulling a 30-foot Jayco White Hawk 24MBH travel trailer. The trip exposed the brilliant engineering, software quirks, and logistical realities of heavy EV hauling. The Hummer EV’s 9,000-pound curb weight and hands-free Super Cruise reduced crosswind sway and mountain driving fatigue, making it an unstoppable towing machine. However, the trip also highlighted the challenges of long-haul EV towing, including a strict 130-mile usable range limit, high fast-charging costs, and the need for meticulous planning. The owner’s experience shows that while the Hummer EV is a phenomenal tow vehicle, it requires immense patience and planning for long-haul trips. The trip’s key takeaway is to charge as high as possible at each stop to minimize the physical headache of unhooking a 7,000-pound trailer. The article concludes that the GMC Hummer EV is a flawed masterpiece, offering a unique combination of power, comfort, and technology, but also requiring significant compromises in terms of range and charging logistics.
