CUCV nomenclature was changed to Light Service Support Vehicle (LSSV) in 2001. In 2005, LSSV production switched to AM General, a unit of MacAndrews and Forbes Holdings. The LSSV is a GM-built Chevrolet Silverado 1500, Chevrolet Silverado 2500 HD, Chevrolet Tahoe, or Chevrolet Suburban that is powered by a Duramax 6.6 liter turbo diesel engine. The various Silverados, Tahoes, and Suburbans that are used provide numerous platforms for different kinds of vehicles. As GM has redesigned its civilian trucks and SUVs from 2001–present, LSSVs have also been updated cosmetically. The Militarization of standard GM trucks/SUVs to become LSSVs includes exterior changes such as CARC paint (Forest Green, Desert Sand, or 3-color Camouflage), blackout lights, military bumpers, a brush guard, a NATO slave receptacle/NATO trailer receptacle, a pintle hook and tow shackles. The electrical system is changed to the 24/12-volt military standard. The dashboard has additional controls and data plates. The truck also can be equipped with weapon supports in the cab, cargo tie down hooks, folding troop seats, pioneer tools, winches, and other military accessories. The Enhanced Mobility Package (EMP) option adds enhanced suspension, 4-wheel anti-lock brakes, a locking differential, on/off-road beadlock tires, a tire pressure monitoring system and other upgrades. About 2,000 LSSV units were sold to U.S. and international military and law enforcement organizations.
