1942 GMC CCKW 352 6x6 1/2 Ton Cargo Truck

GMC's Model CCKW is probably second only to the JEEP in fame as the "workhorse" of WW2. Developed mostly from off-the-shelf civilian components with some military sheetmetal and a second rear axle added, 562,750 of these trucks were produced from 1942 to 1945 by the General Motors Truck and Coach Division of Yellow Truck and Coach Mfg. Co.

No other truck built during WWII came in more variations: It was not only available in 2 wheelbases (145" for the model 352 and 164" for the model 353) but also as a dump, compressor, van, decontamination, cargo, wrecker, chemical service, fuel tanker, water tanker, ordnance maintenance, shop, surgical, water purification and other versions.

Many trucks were also equipped with Heil or Garwood winches and about 25% carried the ring mount for a .50 caliber machine gun The early models had the closed civilian cab which was changed in 1943 to the standard open military cab. The chassis of these trucks had either Banjo or Timken axles which were not interchangeable.

Similar trucks were built by International and Studebaker. While the former went almost exclusively to the Marine Corps in the Pacific theater of war, large quantities of the latter were shipped to Russia under the Lend=Lease program. This is one reason why today only few of these truckks have survived while GMC's are still plentiful, may kept them in service for another 40 years or so, a true testament to their reliability, curability and ease of maintenance.

The truck shown here served in the Danish Army after WWII and was then acquired by a British collector. Its present owner saw the truck at a military vehicle show in England and purchased it in 1993.

The truck is stock in every respect with the exception of the heater.
