What you would lose in mileage (very negligable) you will gain in driveability. Running to high of a gear on the highway can actually cause worse mileage as the trans (auto) may have to drop out of OD for longer periods.....GM found this out the hard way when they used to put a 3.07 ratio in with the 700R4 automatic...severe drop in mileage.
If this was a car, then the 4.10's would be overkill, the rolling diameter of the tire is smaller, which theoretically lowers the gear ratio, or final drive anyway

now that's the kind of answer I was looking for
