I wander what better to have on the truck rear axle 3:55 or 4:10 to pull a 15000 lb FW.What the mile difference driving solo?

I'm happy with 4.30's, but do not drive over 65 mph. Many people have to lock out top gear when towing with lower ratios - My truck is used exclusively for RV duty, so I am happy being able to make most of the drive in 6th gear and the worst hills in 4th.
My truck with 3.42's won't shift into 6th gear until 65 with the TH on. With 385 hp/ 900 lbft running in fifth is basicly like a truck with 4.10's running in sixth. 55 is the shift point from 4th to 5th.
