The Ford F-150 pickup truck has been the best-selling vehicle in the U.S. for more than three decades. It got its start as the Ford Model TT in 1917 after consumers asked Ford for a vehicle that could haul heavy loads and serve as a workhorse. Ford complied and the pickup was born. The Model TT could carry one ton of payload, and in 1928 it was replaced by the Model AA, which had a 1.5-ton chassis. The F-Series had its birth in 1948 covering six truck classes, from a half-ton to a cab-over truck. Power and capacity increased during the second generation, in 1953. The truck continued to evolve with the times, bringing us to the current-generation aluminum-body F-150. Depending on how it’s ordered, an F-150 can be a mud-slinging work truck or a luxurious, leather-trimmed mobile office.
