New 2026 GMC Sierra 3500HD

This 2026 GMC Sierra 3500HD AT4 Crew Cab 4WD in Summit White brings heavy-duty capability together with a cabin that is much more comfortable than the typical work-focused truck. The Technology Package adds a 15-inch Head-Up Display and Rear Camera Mirror, while the AT4 Preferred Package adds a power sliding rear window, universal home remote, and roof marker lamps. A power sunroof, sport steps, and gooseneck and fifth-wheel prep make this particular Sierra even more interesting. Wood Wheaton has this 8.2-foot box AT4 here in Prince George, BC.
