We just returned from a trip with our F-250 FX4 7.3L 10spd 3.55 towing our TT in sig. More than plenty of power. Backing into the side yard through grass and soft ground with plenty of grunt just above idle. In 4 Lo, I have to ride the brake. The only thing 4.30 gears would do is reduce fuel efficiency and make it sound like I needed another gear at the top end.
