The Ford F-Series is a series of light- and medium-duty trucks (Classes 2–7) that have been marketed and manufactured by Ford Motor Company. In production since 1948, the F-Series includes full-size pickup trucks, chassis cab trucks, and commercial vehicles. It has been produced in 13 distinct generations. In 1999, during the 10th Generation, the lineup was separated into the F-Series, which continued with the F150 trucks, and the F-Series Super Duty, which began with a new platform for the more commercial oriented versions such as the F250 and F350.
