History

The CCW-353 (C for 1941 design, C for conventional cab, and W for tandem rear axles) was a near identical version of the CCKW-353, that lacked its front-wheel drive, resulting in an officially purely on-road, and therefore 5-ton rated, 6×4 version of the same truck. A beam front axle was used, with the transfer case locked in high range. Of the ~118,000 2+1⁄2-ton, 6x4 trucks the U.S. built in WW II, GMC contributed 23,649 units of the CCW-353 as standard cargo trucks without winch – almost all of them built in 1942.

Initially, all versions used a modified commercial AK series truck closed cab design having a metal roof and doors. By 1944, an open cab version, with a canvas roof and doors, was used. This was easier to build, and the roof could be removed to lower the shipping height. 1 in 4 of cabs had a machine gun mounting ring above the co-driver's position.

The CCKW provided a platform for the widest range of bodies on any U.S. military vehicle,[citation needed] with the 12 ft (3.7 m) cargo version being the most common. As steel was more heavily rationed during the course of the war, the steel cargo bed was replaced by a wooden one. Wooden beds proved unsatisfactory and a 'composite' bed with steel sides, framing, and wooden bottom slats was developed. However, the composite bed was still unsatisfactory and the bed design returned to all steel. Standard cargo models had beds with fixed sides and a drop tailgate, as well as folding troop seats.

A standard rectangular van configuration was used in communications, medical, workshop, and many other specialty roles. Special built vans were also used.
