The Chevrolet G506 trucks were a series of 1,5-ton 4x4 trucks used by the U.S. Army during and after World War II. Manufacturer - Pontiac West Assembly, Yellow Coach/GM Truck and Coach. Produced 1940Ц45.
During WWII four companies made most of the 1,5 ton trucks for military service; International (M-3L-4) made specifically for the Navy and Marines, Ford (GTB), Dodge (WC62) and Chevy (G506). Of the manufacturers, Chevy by far, supplied the most 1,5 ton trucks during the war. For the Chevy, G506 refers to all 1940 Ц 1945 Chevy 1,5 ton trucks although individual models were further designated by their configuration (a dump is a G7106, cargo is a G7107, etc ).
The Commercial Utility Cargo Vehicle program was instituted to provide the United States military with a family of less expensive vehicles to augment the purpose-built, but high cost, trucks such as the M-561 Gama Goat, M-37, and later the HMMWV. The first attempt to use an off-the-shelf commercial vehicle (with a small number of military upgrades or changes) to augment military tactical trucks was the Kaiser Jeep M-715. The M715 was followed by Dodge M880/M890-series and finally Chevrolet M1008/M1009/M10xx trucks, all rated at 1 1/4 ton capacity (five-quarter).
Commercial Utility Cargo Vehicle or CUCV/LSSV is a vehicle program instituted to provide the United States military with light utility vehicles based on civilian trucks. In 1987, Chevrolet started building a new generation of CUCV. The US Air Force initially bought small batches of these units, dubbed the CUCV II. Produced through 2001, CUCV IIs were basic civilian Chevrolet C/K, Tahoe, and Suburban units sent to another plant for "militarization" on special order.
The K5 Blazer was the smallest full size SUV version of the General Motors C/K Trucks family. Introduced to the Chevrolet line in 1969, the full-size Blazer was replaced in 1995 by the Chevrolet Tahoe. In 1970, GMC introduced its own model of the truck, called the Jimmy, which lasted until the 1992 GMC Yukon. Both were based on the short wheelbase trucks and were available with either rear-wheel drive or four-wheel drive. The Blazer's long wheelbase relative (with an integrated rear body, and doors for 2nd row passengers) is known as the Chevrolet Suburban.
