Change gear ratio on 454 class C
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

Maybe 3.73 but not 3.23. 3.23 will cause engine with the weight of MH will lug down.
More specifically, it will have to downshift to first gear and rev up very high just to get up small hills, well below posted speed limits. Potentially dangerous.
