The Commercial Utility Cargo Vehicle or CUCV Program was instituted to provide the United States military with a cheaper Light Utility Vehicle to augment the purpose-built, but expensive, Gama Goats and M151 series "Jeeps" approaching the end of their service life. It initially provided Dodge D Series and then Chevrolet C/Ks with several military modifications. The vehicle has five basic configurations; cargo, utility, ambulance, shelter carrier, and chassis. The vehicles were purchased in the late 1970s and early 1980s from Chrysler Corporation, Dodge Division, and in the mid-1980s from General Motors Chevrolet, and GMC Truck divisions.
