23. Chevrolet C30 One-Ton Dually
Officially, this truck is part of the third-generation C/K model. However, it’s so important it needs to be on this list. Chevrolet introduced it in 1973 as a part of a big Chevrolet push on the global truck market. The C30 One-Ton Dually was the first crew cab dually they offered for sale and arguably the first heavy-duty truck ever.
Today, most car manufacturers produce heavy-duty trucks in various configurations. But back then, nobody offered a dual model with space for six passengers, heavy-duty components, and a long bed. In 1973, when Chevrolet offered the C30 One-Ton Dually, it soon became popular and influential. They equipped it with Chevrolet’s biggest gasoline 454 V8 and a four-speed transmission, but an automatic was also available.
