The interior reflects attention to detail with genuine wood accents, perforated leather seating surfaces, and a genuine wood dashboard insert. Climate control extends throughout the cabin with front dual-zone air conditioning and rear window defogger, while the heated steering wheel adds comfort on cold mornings.
The Duramax diesel delivers the torque needed for serious towing and hauling, complemented by the gooseneck and 5th wheel prep package that includes a hitch platform and stamped bed holes ready for your trailer equipment. The 2-speed active transfer case and off-road suspension provide capable handling across varied terrain, while hill descent control offers additional confidence on challenging descents.
Technology integration keeps you connected and informed. The premium GMC infotainment system works seamlessly with Apple CarPlay and Android Auto through wireless phone projection. Safety systems surround you with automatic emergency braking, forward pedestrian braking, and a comprehensive camera system featuring HD surround vision and trailer camera provisions for confident maneuvering in any situation.
The exterior wears Downpour Metallic Blue with signature chrome Denali grille badging, spray-on bedliner with GMC logo, and LED smoked amber roof marker lamps that announce your presence with style. Deep-tinted glass protects the interior while the power sliding rear window with defogger adds practical functionality.
This Sierra 2500HD Denali offers the capability to handle demanding work while delivering the refinement expected in a premium truck. We invite you to schedule a showing and experience this diesel-powered capability firsthand.
