For 2011, Ford has taken its F-250 (three-quarter-ton), F-350 Super Duty (one-ton), and F-450 pickups and infused them with even more of the things owners hold in high regard--namely powerplants. Super Duty trucks are ideal for towing and hauling, and a host of new features such as Hill Ascent and Hill Descent Control, make the task even easier, while giving drivers added piece of mind.
