About the 2010 GMC Sierra 2500
2007-2010 Sierra HD generation (GMT900 HD), final year before the redesigned 2011 heavy-duty truck.
GMC positions the Sierra 2500 HD as a heavy-duty pickup for serious towing and hauling that also offers a more polished look and cabin than its Chevrolet Silverado HD sibling. Its core appeal is straightforward: strong work capability, broad cab and bed choices, available diesel torque for big trailer duty, and trims that range from basic job-site use to leather-lined comfort for owners who tow often but still want a nicer everyday cabin.
The 2010 Sierra 2500 HD spans a basic Work Truck, the more everyday-friendly SLE, and the comfort-focused SLT. Work Truck emphasizes durable jobsite basics, SLE adds cloth seating and useful convenience features, and SLT brings leather seating, power-adjustable front seats, Bose audio, and dual-zone automatic climate control. Gas and diesel V8 models use a 6-speed automatic transmission.
