The Mack F series was the third generation of cabover trucks from Mack Trucks. Its production began in 1962 and ended in 1981. It was produced primarily as a set-forward axle truck but a setback axle version was shipped overseas (from the USA). The cab came in a 50 inch (1371.6mm) day cab (no sleeper). Sleeper models included a 72 inch (1828.8mm), 80 inch (2032mm) and later a "bustle back" was added that lengthened the sleeper to 86 inches (2184.4mm).
