I've got 98 coachman class C 454 with 4:11 rears. I want to improve mileage by going to 3:23 gears. Will this work? Thanks

The next time you put tires on it, just install tires with a larger diameter. This changes the overall drive-train ratio just as if you had lowered the differential gears down from 4.11.

As a bonus, you also get longer tread life and better ground clearance with the larger diameter tires.
