Quick Answer
The 3100 is Chevrolet's designation for a half-ton pickup on the short wheelbase. In the same system, 3600 meant a three-quarter-ton and 3800 a one-ton. The 3100 covers the Advance Design (1947-1955) and Task Force (1955-1959) trucks, the classic early Chevy pickups.

The number is a load-and-wheelbase code, not a model name.
