Does anyone know if changing just the 3.93 rear end back to the 3.21 on my Rebel would provide the same fuel economy as the standard 1500? I rented a Big Horn Edition a few times and got over 20 MPG traveling with plenty of power to spare. I get between 12.7 and 15.5 MPG with my Rebel. All other motor and gearing seem to be identical, its just the rear end gears.
