Advance-Design was a truck series by Chevrolet, their first major redesign after WWII. It was billed as a larger, stronger, and sleeker design in comparison to the earlier AK Series. First available on Saturday June 28, 1947, these trucks were sold with various minor changes over the years until March 25, 1955, when the Task Force Series trucks replaced the aging Advance-Design model.
The same basic design family was used for all of its trucks including the Suburban, panel trucks, canopy express and cab overs. The cab overs used the same basic cab configuration and similar grille but used a shorter and taller hood and different fenders. The unique Cab Over fenders and hood required a custom cowl area which makes the Cab Over Engine cabs and normal truck cabs incompatible with one another while all truck cabs of all weights interchange.
From 1947 until 1955, Chevrolet trucks were number one in sales in the United States, with rebranded versions sold at GMC locations.
In 1951 doors now have vent windows, mid-year change from 9-board bed to 8 boards per bed. Last year for 80 MPH speedometer, chrome window handle knobs, and chrome wiper knob. New serial number codes: JP 1/2 ton, JR 3/4 ton,& JS 1 ton.
