wheelbase 1950 1/2 ton

Chevrolet engineers included three pickup truck types in the new Advanced Design Series in three-sizes, half-, 3/4- and one-tons (models 3104, 3604 and 3804 respectively) with cargo boxes 78 inches, 87 inches and 108 inches long.

All three boxes were 50 inches wide, 16 1/4 inches high on the sides and 14 inches high in the ends. Wheelbases were 116, 125 1/4 and 137 inches. For each model the cargo box was shifted forward for better distribution of the load in relation to the rear axle and for better support by the frame rails. All pickups continued to be built with wooden cargo floors covered with steel skid strips.
