1967, the cab design has changed only in 1980 and in 2000. Redesigned on an all-new chassis, the 2016 F-Series medium-duty trucks retain an updated version of the 2000–2015 F-650/F750 cab. The medium-duty F-Series served as the donor platform for the B-Series cowled bus chassis produced from 1948 to 1998. Produced primarily for school bus bodies, the B-Series was discontinued as part of the sale of the Ford heavy-truck line to Freightliner in 1996. Heavy-duty trucks Above its medium-duty truck ranges, the Ford F-Series was used as a heavy-truck chassis during its early production. In 1951, Ford debuted its "Big Job" line, denoting the F-8 conventional. In 1958, the "Super Duty" and "Extra Heavy Duty" replaced the Big Job trucks, marking the debut of the Super Duty V8 engine line. In 1963, the N-Series became the first short-hood conventional built by Ford, replacing the F-900 Super Duty/Extra Heavy Duty. Although based on an all-new chassis and separate bodywork, the cab was sourced from the F-Series. In 1970, Ford introduced the L-Series "Louisville" line of conventional trucks, moving all heavy truck development away from the F-Series. The L-Series/Aeromax would remain in production through 1998, as Ford exited the North American heavy-truck segment. Outside North America, Ford builds the Ford Cargo, and Ford F-MAX. Vans From 1948 until 1960, the F-Series was produced in a panel van configuration; in contrast to General Motors, Ford never offered a passenger "carryall" variant (competing against the Chevrolet/GMC Suburban or the International Travelall). For 1961, the panel van was discontinued, largely replaced by the Econoline compact van. From 1968 to the present day, the Econoline/Club Wagon/E-Series vans have shared a degree of mechanical commonality with the F-Series pickup trucks (during the 1970s, some body components were shared). While no longer produced for retail sale, the E-Series still shares its engines and transmission with the Ford Super Duty trucks.
