The standardized 5-ton M39 series was produced by the AM General Company a short time, gathering the last of 112 thousand trucks in this range. As early as 1970, constructors of other manufactures begun to develop a new updated range, but this work was completed by the AM General Company. At the end of 1971, in South Bend, producing of the new 5-ton range M809 (6×6) with GVW 14,0-15,2 t was begun. It was equipped with a new Cummins NHC250 diesel engine (14,0 l, 243 hp), mechanical 5-speed gearbox, dual main gear, hydro pneumatic braking system, steering booster and 24-volt electrical equipment.

The next versions were produced:

The intake on the M809 series trucks was located on the left side of the hood, while on the M39 trucks – on the right side. The M809 series had the same cab as the M39, but the hood was longer to accommodate the more powerful engine. In the U.S. Army the 5-ton medium tactical vehicles (MTV) of the FMTV series replaced remaining M-809 series trucks in the early 1990s, while in the U.S. Navy and Marine Corps the Medium Tactical Vehicle Replacement (MTVR) superseded both the M-809 and M-939 series of trucks after 1999.
