2015 GMC Sierra 2500HD SLT

The Sierra 2500HD is GMC's heavy-duty pickup, built for serious towing and hauling work. It drives with the solid, planted feel you want in a heavy-duty truck, though the steering is a bit vague on center. The ride is firm and truck-like, especially when unloaded, which is the trade-off for its payload capacity. Crew cab models offer a roomy back seat, and the bed is sized for real work, with available features like a tailgate step. The SLT adds leather upholstery, heated front seats, and a larger touchscreen over the SLE, making it the comfort-oriented choice in the Sierra 2500HD lineup.
