One of th rare cases where math is your friend. But be honest - if you want MPG buy a Cruze and use your truck only when desperately needed.

I'm not expecting superior fuel mileage with this truck. I just want to do whatever is cost/time-effective to try to get "good" mileage (10-14mpg). I will research the torque curve and try to optimize it that way. Like I said before, I heard that 2200rpm @ 65-70mph is ideal. By my calculations I would need 4.56 gears to do this.
