Quick Answer
The C10 is the half-ton Chevrolet pickup and the C20 is the three-quarter-ton, one weight class up. They share the same cab and styling, but the C20 has heavier springs, axles, and brakes for towing and hauling, with a firmer ride. The C designates two-wheel drive (K is four-wheel drive).

The number is the load rating.

C10 (half-ton)

The lighter, smoother-riding, most popular C/K.

C20 (three-quarter-ton)

Same looks, stouter underpinnings for real work. It rides firmer but tows more. A C20 gives you the same square-body or earlier styling with more capability.
