Used 2013 Gmc Sierra 3500 HD Denali

The 2013 GMC Sierra 3500HD Crew Cab Denali blends rugged capability with upscale refinement. Powered by a stout 6.6 L Duramax turbodiesel V-8 mated to a smooth Allison 6-speed automatic and 4WD, it delivers hearty torque (around 765 lb-ft) for towing heavy loads with confidence. The crew cab offers full-size comfort for five, while the 6½-ft bed handles serious payloads. Premium touches—including leather seats and Denali trim—elevate the interior, while features like stability control, trailer-sway management, and optional rearview camera boost safety. Whether hauling heavy trailers or cruising in comfort, this Denali stands out as both a workhorse and a luxury truck.
