Going mechanical will be simple to do with all the right parts and as you are going in with the manual, that will help. My neighbor has a '94C2500 that must have 3.7x gearing, with the auto and she says on the highway, 65mph with cruise control on she sees 23mpg. I have heard rumors of manual tranny 3.4x geared C2500 getting 25-27mpg.

The frontal area of the 2wd is much lower to the ground and a bit of less weight vs the 4wd chassis. With the factory air dam, my mpg did go up.

Why put the heavier and wider 255 tires compared to the 235s?
