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 Humvees then coming into service. It initially provided Dodge D Series and then Chevrolet C/Ks with several military modifications. All were phased out sooner than expected due to their inability to survive the hardships that the purpose built vehicles could endure. 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.
