New 2026 GMC Sierra 3500HD

Onyx Black gives this 2026 GMC Sierra 3500HD Denali Crew Cab 4WD an especially commanding look, with chrome details and bright machined wheels adding the polished finish expected from a Denali. The 6.6L Duramax turbo-diesel provides the heavy-duty foundation, while the Denali Reserve Package brings a power sunroof, Rear Camera Mirror, and 15-inch head-up display into the experience. This one also has a 6.8-foot box and gooseneck and fifth-wheel preparation, giving it plenty of flexibility when there is serious work to be done. It is an impressive combination of strength and comfort for driving in and around Prince George, BC.
