2017 GMC Sierra 3500HD Denali

The Sierra 3500HD is GMC's heaviest-duty pickup, built to tow and haul serious loads that a half-ton truck can't handle. It rides like a heavy-duty truck, so you feel the road, but the steering is direct and the brakes are strong enough to handle a loaded bed. The cabin is roomy and straightforward, with big controls that are easy to use even in work gloves, and the Denali adds upscale leather and trim. You can get it as a regular, double, or crew cab, with a bed long enough for plywood and a payload rating that means real work. Shoppers who want the nicest heavy-duty pickup pick the Denali over the SLT, with its richer leather, real wood trim, and standard bells like heated and cooled seats. Underhood is the burly 6.6L V8, making 360 horsepower and 380 lb-ft of torque, routed through a six-speed automatic and four-wheel drive that makes light work of a loaded trailer. The Denali's ride is tuned for highway comfort, which is welcome on long hauls, but you'll still feel every expansion joint with an empty bed.
