General Motors' first major redesign post-World War II, the Advance Design series was billed as a bigger, stronger, and sleeker design. 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. From 1947 until 1955, Chevrolet trucks were number one in sales in the United States. While GMC used this front end, and to a slightly lesser extent the cab, on all of its trucks except for the Cab Overs, there are three main sizes of this truck. The half-,... three-quarter-, and full ton capacities in short and long wheelbase. 1947 - Gas tank filler neck on passenger side of bed. No vent windows in doors. Hood side emblems read "Chevrolet" with "Thriftmaster" or "Loadmaster" under it. Serial numbers: EP 1/2 ton, ER 3/4 ton, & ES 1 ton. 1948 - Manual transmission shifter now mounted on column instead of floor. Serial numbers codes: FP 1/2 ton, FR 3/4 ton, & FS 1 ton. Early 1949 - Gas tank now mounted upright behind seat in cab; filler neck aft of passenger door handle. New serial number codes: GP 1/2 ton, GR 3/4 ton, & GS 1 ton.
