2026 GMC Sierra 3500HD

HIGHLIGHTED FEATURES Dual rear wheels, the Duramax 6.6L turbo-diesel, and factory gooseneck and 5th wheel prep put this Sierra 3500HD Denali squarely in heavy-hauling territory. A trailer brake controller, HD Surround Vision with a bed view camera, and Trailer Side Blind Zone Alert make lining up the hitch and changing lanes far less stressful. The Denali Reserve Technology Package adds a head-up display, rear camera mirror, and power sunroof to a cabin with heated and ventilated front seats, heated rear seats, Bose sound, and a 13.4-inch touchscreen with Google built-in. Snow plow prep, upfitter switches, a high idle switch, and the MultiPro tailgate show it was ordered to work, not just to look good. Hitch up the fifth wheel and the drive becomes the easy part of the trip.
