I just got back from a trip to west tennessee, round trip 700 plus miles. It's confirmed my truck loves gas, I got exactly 14 miles per gallon. I knew it was something close to that before I left because it only gets between 9 and 10.6 in town. The only thing I can contribute this to is the 4:10 gears, My 04 hit 20 a time or two and usually got around 13/14 regularly in town, it had 3:73 gears..
