What gears do you have, 4.10's? if so that was probably a mistake, I have the cab chassis and could only get 4.10's with the Aisin 6 auto, I'm averaging 11 mpg hand calced at only 3500 miles and my truck weighs 11,500#, when loaded and towing over 22,000# CGVW, (only maybe 5-10% of the time towing). Plus only about 15% of highway driving
I was bummed when I was getting under 10 with the first couple of tanks but am happier now, one thing I learned is don't kitty foot it, at least with my truck it does not seem to help at all, when I stomp it, the average MPG on the overhead goes up.
If you do have the low gears maybe you could get the higher gears, by far the vast majority of guys here have the high gears in the pick ups from what I've read, with no lack of towing ability.
