New 2026 GMC Sierra 3500HD

This 2026 GMC Sierra 3500HD Denali Crew Cab 4WD does exactly that, pairing the 6.6L Duramax turbo-diesel with the Denali Reserve Package and an 8.2-foot box. Summit White keeps the exterior clean and classic, while chrome details give the Denali its unmistakable upscale presence. For buyers around Prince George, BC who want a truck built for substantial work without giving up comfort, this one has a lot going for it.
