but it will tow like a pig trust me. our expy had the 3.73 my codrivers F150 has 3.31 I have used both to tow my car trailer and race truck and the expy will tow circles around that F150 even though it's heavier.
Oh and BTW his F150 MIGHT get 1mpg better when we took a trip together running the same road as well as on an average, his claim is 14-15 mine is steady 14.
