The 2016 Ford Super Duty is the big brother of the best-selling vehicle in America - the F-150. Where that light-duty truck's capabilities end, these heavy-duty ones begin. Available as the F-250, F-350 and F-450, the F-Series Super Duty trucks are built for heavy towing and professional applications. In other words, these are trucks that thrive as being workhorses rather than mere family haulers or office commuters. Even so, while many of the basic models will live their lives as work trucks in fleets, a 2016 Super Duty can be outfitted with luxury-car levels of features and amenities. The F-Series line of heavy-duty pickups comes in a wide variety of cab and bed configurations, offered with stout gasoline or diesel engines.
