With my choice main and aux trans and rear end I may be able to get tall enough gears in double over to get the same mpgs in a 2 ton so long as those giant tires don't drag me down. Just thoughts..

Mine now gets 9.5-10.0 MPG towing the Jeep & trailer @ 65MPH.
Total 20,000 weight. That is with 3.58 rear axle.

Not towing when it had the 3.70 gears @ 13,000 lbs it got 11.7MPG on a 50 mile interste test run
