Have a home builder budy with one. Dont expect great mileage. I had an old full size bronco with 4.56 gears and 33's(same as powerwagon) and it was OK(mpg) around town. and quite peppy. At hwy speeds it was a little on the high RPM side, but managable. Great truck for 4wheelin. Standard winch, disconecting sway bar, and locking diffs why not get another diesel?
