2010 GMC Sierra 2500HD Extended Cab
Three-Quarter-Ton Truck
This Sierra is meant for those who need to haul serious loads. The gasoline V8 is both powerful and responsive, and the optional turbo diesel is a tow king. Off-road capabilities are enhanced with an available full 4x4 drivetrain with low-range transfer case. There is an array of styles, including passenger cabs that has a regular cab holding up to three people, a four-door extended cab for up to six, and a crew cab that still can seat six (only five with an optional front bucket seats) but offers 4.4 more inches of leg room in the rear. It is also available in standard box (6'6') or long box (8'2'). This model Sierra 2500's variety and abilities have earned it recognition from JD Power for its initial quality and a recommendation from Consumer Reports.
