2021 GMC Sierra 2500HD Denali

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 Denali is the top Sierra 2500HD trim, so you give up the AT4's off-road focus for more luxury and a higher price tag. Under the hood is a 6.6L V8 with 401 horsepower and 464 lb-ft of torque, paired with a six-speed automatic and four-wheel drive. The Denali's standard MultiPro tailgate and HD Surround Vision make hitching up a trailer noticeably easier.
