However, if it can help prevent a downshift, or allow shifting earlier, that's something.

Are you referring to pumping losses? Can you elaborate more on that?
What does RV stand for? I'll be sure to take a look.
In my specific situation a higher gear ratio won't help me. The 4.0 is most efficient from like 2200-2600 rpm. I would like to keep highway cruising within that range. Plus I am getting larger tires for off roading so I would like to get lower gears for that... Maybe 4.56:1.
Some people might think my goals are complete opposites but I just want the best of both worlds!
