FORD F-150 AXLE RATIO CHOICE

I agree the 10-spd trans (I have a vehicle with 9-spd) makes a huge difference and final drive means less. Axle ratio makes a difference for 6spds in RV owner experiences. But there is no justification for a lower axle ratio. It certainly isn't fuel economy for anything except the US Government fuel rating drive cycle. If you are compromising for something on a lot that you have to get in under a month - maybe.

I also agree payload is more important than axle ratio for this truck. I also recommend getting the largest fuel tank available.
