Chevy CUCV M1008 M1009 M10xx Trucks
The family of Commercial Utility Cargo Vehicles (CUCV, pronounced cuck-vee) began with the Kaiser Jeep M-715 and expanded to a large fleet with the Dodge M880 series trucks, procured from Dodge during 1976 and 1977. The gasoline powered Dodge vehicles were soon discarded however, replaced by more robust diesel trucks from General Motors' Chevrolet Division. The M715 was not called a CUCV, and originally neither was the Dodge M880/M890 series. The name Commercial Utility Cargo Vehicle (CUCV) originated with the Chevrolet M10xx series vehicles and was retroactivly applied as well to the similar Dodge trucks.
Chevrolet CUCV Family of Light Trucks
Production and deliveries of the General Motors commercial utility cargo vehicles (CUCVs) began in February of 1984. The new 1 1/4-ton vehicle had a 6.2 liter diesel engine that was derived from the four-wheel drive Chevrolet and GMC pickups and utility vehicles sold commercially as Blazers and Jimmys. CUCVs came in several configurations: cargo, shelter carrier, utility, and ambulance models. The CUCV replaced the M880s and represented the first major military vehicle production undertaken by General Motors since World War II.
Initially, the diesel-powered Chevy CUCV was seen as far superior to the replaced vehicles. The CUCV has better traction. Its storage capacity is twice that of a jeep. The CUCV is equipped with improved air and gas filtration systems and its gas mileage is much better. Initial hopes for the CUCV were that it would be able to fully substitute for custom built military tactical trucks in many roles. However, in actual field use, the CUCV did not live up to its promise. Particularly in the Gulf War, where harsh desert conditions and primitive infrastructure put all military equipment to a severe test, the CUCV was highly disappointing. As a result, the CUCV trucks were phased out sooner than expected, unable to survive the hardships that the purpose-built military vehicles could endure. The Chevrolet CUCV lingered into the late 2000s but was eventually replaced by variants of the HMMWV in most military units.
The Chevrolet Commercial Utility Cargo Vehicle (CUCV) series, like its M880-series predecessor, was a militarized version of a commercial off-the-shelf (COTS) truck. Features of the Chevy CUCV trucks include these items as standard or optional add-on kits:

Individual Models of Chevrolet CUCV
The Chevrolet CUCV Family of Light Trucks includes these models and variants:
The M1008 base chassis is used for most of these vehicles, including the M1010, M1028 and M1031. By removing the special bodies mounted to the chassis, the M1008 chassis can be recovered and used with a pickup body.
Chevrolet CUCV Electrical System
The Chevrolet CUCV electical system is a hybrid 12/24 volt, using standard automotive 12v components for lights and instruments while using a military 24v starter. The standard system has two 12v batteries (Delco 1200 or military-type 6TN) in series and two 100 amp alternators (Delco 27-S1), wired in series to produce 24v. A NATO slave cable receptacle is wired to the 24v circuit so any 24v military vehicle can be interconnected for jump starting. The CUCV 27MT starter motor is a heavy-duty part, with increased strength pinion and ring gear teeth. Temperature self-regulating AC 13G glow plugs operate on 12v supplied by the 24v circuit through a resistor to drop the voltage.
The M1010 Ambulance and some of the M1028 trucks (with the S250 shelter) are equipped with a heavier 200 amp 12/24v system, that uses two batteries (Delco 1200 or military-type 6TN) and two 24v 100 amp Leece/Neville alternators. The 200 amp M1028s have not been provided with a different model designation.
