For comparison, one of my hunting buddies had a Toyota Tundra with a 305 sized motor that would get 22~24 at highway speeds but that truck came with all of the modern aerodynamics and computerized gizmos.

I drive a 2017 Tundra with a 5.7 and 6 speed trans at work everyday and the best I can get is 16 mpg.
