The F-Series is a series of full-size pickup trucks from Ford Motor Company which has been sold continuously for over six decades. The most popular variant of the F-Series is the F-150. It was the best-selling vehicle in the United States for 24 years, currently (2007) the best-selling truck for 34 years, and the best selling vehicle in Canada, though this does not include combined sales of GM pickup trucks. In the tenth generation of the F-series, the F-250 and F-350 changed body style in 1998 and joined the Super Duty series.
During the post-World War II era, smaller Canadian rural communities had access to either a Ford dealer or a Lincoln-Mercury-Meteor dealer, but not both; a Mercury-badged version was sold at Lincoln-Mercury-Meteor dealers there from 1946-1968. Other than the grilles, trim, and badging, these trucks were identical to their Ford counterparts.
The first F-Series truck (known as the Ford Bonus-Built) was introduced in 1948 as a replacement for the previous car-based pickup line introduced in 1941. The F-Series was sold in eight different weight ratings, with pickup, panel truck, cab-over engine (COE), conventional truck, and school bus chassis body styles.
The first-generation Ford F-Series is a series of pickup trucks and commercial vehicles produced by Ford Motor Company. Introduced in 1948, the F-Series was the first post-war truck design from Ford. In a break from previous Ford trucks, the F-Series was no longer based upon its car chassis, but on a dedicated truck platform. This generation of the F-Series would remain in production until 1952. F-Series trucks were assembled at sixteen different Ford factories. Serial numbers indicate the truck model, engine, year, assembly plant, and unit number. The most common model was the F-1 with a 6 ½-foot bed followed by the F-2 and F-3 Express models with an 8-foot (2.4 m) bed.
The first F-Series truck (known as the Ford Bonus-Built) was introduced in 1948 as a replacement for the previous car-based pickup line introduced in 1941. It had a flat, one-piece windshield and integrated headlamps. It had a wider cab. Options included the “See-Clear” windshield washer (operated by foot plunger), passenger-side windshield wiper & sun visor, and passenger-side taillight. The F-1 truck was also available with additional chrome trim and two horns as an option. All F-series were available with optional “Marmon-Herrington All Wheel Drive” until 1959.
Design of the F-Series truck changed tremendously from 1950 to 1954. From 1948 to 1950, the grill was a series of horizontal bars and the headlights were set into the fenders. For 1951 and 1952, the headlights were connected by a wide aerodynamic cross piece with three similarly aerodynamic supports. The rear window was wider in the later trucks and the dashboard was redesigned.
The F-Series was sold in four basic models. Along with the pickup truck (F-1 through F3), the F-Series was sold as a panel truck (based on the pickup), COE/cab-over engine chassis (F-5 and F-6, branded C-Series) and school bus chassis (F-5 and F-6, branded B-Series). Above the F-5, the F-Series was a medium-duty and heavy-duty conventional truck sharing the bodywork of the smaller F-Series.

F-1: 1/2 ton (4,700 GVWR max.)
F-2: 3/4 ton (5,700 GVWR max.)
