In 1947, Chevrolet launched a major redesign of its pickup truck offerings, known as the Advance Design series. One of the most distinctive features of these trucks was the Deluxe Cab option, which included a pair of curved "Nu-Vue" corner windows at the back of the cab, increasing visibility and giving the truck an open feel. This remains a sought-after design today. Enthusiasts typically refer to it as the "5-window" Chevy.
