2012 Chevrolet Silverado 2500HD & GMC Sierra 2500HD Truck Review – Heavy Duty trucks are big and buff and can tow a house it seems. While Ford recently redesigned their F-150 line and introduced a new engine, GM did the same but took it one step further. The 6.6 liter diesel V-8 engine produces 397 horsepower and 765 lb-ft. of torque. The frame is now fully boxed which helps the Sierra and Silverado HD trucks tow over 21,000 pounds. There are a bunch of new technological features to help with payload and towing capabilities like: trailer sway control, hill decent assist, diesel exhaust brake, and stabilitrak.
