From wiki:
The GM CUCV's were produced in the 1984-86 time period (mostly 1984) and were powered by 6.2L Detroit Diesel V8 engine. The GM CUCVs were assembled mostly from the heaviest duty bits and pieces from the light commercial truck lines. The CUCVs came in three basic body styles, a pickup, a utility and an ambulance body. A chassis cab fitted with a service body could be called a fourth. They were given “M” numbers and the trucks were all rated as 1-1/4 ton (commonly called a “five-quarter”), even though some of them had payloads in excess of that. The M1008 was the basic 5/4 cargo truck, the M1010 was the ambulance and the M1009 3/4 ton utility rig, which was a stripped Blazer uprated to 3/4-ton capacity. In the truck lines there were some heavy duty variants, to include the M1028, M1028A1, M1028A2 and M1028A3 shelter carriers, the shelter being a mobile command or communications enclosure. The M1031 was the chassis cab which was most commonly found in the two door version. These latter trucks were all rated for heavier 3,600 or 3,900 pound loads, vs. the M1008s 2,900 pound load capacity. The M1028A2 and A3 models had dual rear wheel Dana 70 axles and are uncommon.
All the CUCVs were powered by GM’s 6.2L J-series Detroit Diesel V8 engine non-emissions diesel. These were rated at 135 hp (101 kW) and 240 lb·ft (325 N·m), which was 5 hp (3.7 kW) more than the emissions gasoline engine of the time. They were all equipped with the TH-400 automatic. All but the M1028A1 and M1031 used the NP-208 chain drive transfer case. The M1028A1 and M1031 units had a slip-yoke rear output version of the NP-205, which was specified mainly for its PTO capacity.
The M1009 Blazer used a standard 10-bolt front axle, but had a 10-bolt in back with an Eaton Locker (“Gov-Lok”) and 3.08:1 gears. The trucks all used open Dana 60 front axles, with the M1028 and M1031 series rigs having a Trac-Lok limited slip. In the rear, the M1008s used the beefy GM 10.5-inch (270 mm) “14-bolt” rear axle with No-Spin lockers (the commercial trade name for the Detroit Locker). Axle ratios were 4.56:1, though the duallies are reputed to have had 4.88:1.
As with other military vehicles, the CUCVs used a 24-volt electrical system. It was actually a hybrid 12/24-volt system that used 24-volts under the hood, complete with dual 100 amp alternators, the mandatory NATO slave receptacle for jump starting any NATO vehicle, and hookups for military radios. The rest of the truck was 12-volt.
GM produced some 70,000 from 1983 to 1986 most for the military. For the past several years, GM Defense has been working over the newest GM trucks as CUCV-II and CUCV-III units for a new generation. The older Dodge M880s were used on the battlefield in some of the brush wars of the early 1980s and the results were reported to be “disastrous.” Likewise, the GM CUCVs saw combat time in Desert Storm and as one unit commander said, the results were “less than desirable.” As a result most CUCV's were replaced by the same HMMWV's they were to augment.
The GM CUCV may not have made the grade as a battlefield vehicle, but it served well in its original role as a dollar-saving bridge between out-and-out tactical vehicles and dedicated civilian vehicles. Like the rear echelon human troops, they provided support for the major goals of the military, namely to project a mighty frontline tactical fist wherever needed. There are still many CUCVs wearing green but there are also many that have passed through the surplus gates into civilian life
