9. Chevrolet Cameo
Before the 1955 to ’58 Chevrolet Cameo, pickups had a step-side design in the truck bed. It was a production method that dated to the first trucks from the early 1920s. But as one of the biggest pickup manufacturers in the U.S., Chevrolet introduced the fleetside truck bed for the 1955 model. The truck bed looked more elegant because it was flush with the lines of the cabin and the whole design of the truck. Second, the fleetside design allowed for the use of the maximum width of the truck bed, making the truck more capable to carry a wider load.
The first model to feature this construction solution was the Chevrolet Cameo, but it wasn’t successful at first. The Cameo was an upscale version of a standard Chevy truck. It featured a V8 engine and updated equipment, and some earlier versions even featured a fiberglass fleetside bed instead of steel. They discontinued the Cameo as a model in 1958, but the fleetside style continues to this day.
