Winner: Chevrolet Silverado HD
Runner-Up: Ford Super Duty F-450

This category focuses on the biggest monsters on the road, the baddest tow machines money can buy. All three power pullers are excellent trucks, and you can't go wrong choosing any of them, but the Silverado/Sierra HD with the Duramax and six-speed transmission is tough to beat. This truck offers an excellent package overall--the most horsepower and torque, fantastic payload capacity, and the best ride characteristics, loaded or unloaded. Ford's towing and hauling numbers continue to be stellar, as the F-450 is best among its competitive set.
