best rpm 870

Rawze you say you get better mileage when you run one gear down do you suppose that has something to do with that your are running in a direct gear instead of turning an overdrive which is harder to turn. I know that some of the bigger companies have gone to direct drive transmissions and have had a couple trucks that came with the 16 speed ultra shifts direct and even tho we turned the same rpms my other ones had 13 speeds and the 16 speeds would out pull them in the rolling hills when we stayed in the top gear. im always curious about messing around with gear ratios and tire sizes but to cheap to really go out and give it a valiant effort.
