1940 Chevrolet Suburban (1935-40 Generation): Chevrolet offered the body style as a "Carryall Suburban". It shared the front sheetmetal and frames of the 1/2 ton pickup models of the same year, but featured all-metal wagon bodies differing very little in shape from contemporary "woodie" wagons. Seating for up to eight occupants was available, with three in front row, two in the middle row, and three in the rear row. Either the side-hinged rear panel doors or a rear tailgate/lift window could be selected for cargo area access.
