General Motors’ first major truck 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.
Introduced in 1947, the Advance Design series pickup was the first major post-World War II truck redesign by GM. Many of the redesign features could be seen as early as 1942, as a part of Harley Earl’s GM Styling Section, including headlights integrated into the front fenders, a tall hood, and a split windshield. Being billed as a bigger, stronger, and sleeker design, the 1947 Chevrolet Advance Design truck featured a gas tank filler neck on the passenger of the bed. The truck also excluded the vent windows in the doors featured on previous models. The grill featured five horizontal bars topped by a hood ornament with a blue bow tie and Chevrolet lettering. The hood side emblems read “Chevrolet” atop a “Thriftmaster” or “Loadmaster” emblem. The truck’s three different serial numbers for the 1947 Advance Design pickup included the EP 1/2-ton (3100), the ER 3/4-ton (3600), and the ES 1-ton (3800). The ¾-ton and 1-ton trucks received the same new styling but had a longer wheelbase and bed.
The cab and fenders on the 1947 Advance Design pickups were the same color. Vehicle options for the 1947 Chevrolet Advance Design included rearview mirrors, heavy-clutch, double-acting rear springs, wide running boards, oil filter, cab rear corner windows, and various tire options. 1947 was also the first year that GM offered radios as an “in-dash” option.
