In January 1918, Chevrolet introduced its first purpose-built truck models (in half-ton and one-ton ratings) aimed at commercial buyers. A century later, pickups are a mainstay of Chevrolet’s domestic business, and in celebration of the milestone anniversary, Rich Scheer, director of exterior design for Chevy trucks, has named the 10 most influential truck designs from the brand.

The 1918 One-Ton, or Model T (disregarding Ford’s automobile with the same name), was Chevrolet’s first purpose-built truck, inspired by the no-frills vehicles used to transport components and goods within manufacturing plants. Powered by a 224-cu.in. “FA” four-cylinder engine rated at 37 horsepower, the worm-drive truck could be ordered as a bare chassis for $1,325; as an open-top Flare Board Express for $1,460; or as a covered-top Eight Post Curtain Top for $1,545. In its debut year on the market, Chevrolet produced 359 Model T trucks, along with 520 Model 490 half-tons.

What're the rest of Chevy's most iconic pickups? Can you guess one? Did you own one?
