Miles Overview
The Sierra 2500HD is GMC's heavy-duty pickup, built to tow and haul serious loads while offering more comfort than the work-truck norm. It squares off against the Ford Super Duty and Ram Heavy Duty, all three fighting for buyers who need real towing capacity. The steering is direct for a truck this size, and the brakes feel strong even when you're loaded up. Expect a firm ride when empty, which is the trade-off for the payload and towing capability this truck is known for. The cabin is roomy and quiet, with available leather and a large touchscreen that make long hauls more pleasant. The SLT gives up the Denali's chrome and leather for a lower price, keeping the same powertrain and capability. Its 6.6L V8 makes 401 horsepower and 464 lb-ft of torque, routed through a six-speed automatic and four-wheel drive that handle heavy loads without breaking a sweat. The SLT can be ordered with the ProGrade Trailering package, which adds a camera system and trailer brake controller for easier hitching.
