So technically It would also be better for Trans then too plus the maybe "added" 1 or 2 mpg's ?
Did you have the big tow option ? What gear ratio did you go with ? And can you do any gear ratio with any locker?I use to use 4th because the truck strugged in 5th too much, idk if it was saving/costing mpg, but i know it was less stress on the drivetrain. Now that i have gears though, i leave it in 5th all the time.
