Gear Ratio on '12 6.7

Everyone,

I am new to site but not new to Fords. Been buying them since 85. Will buy '12 late summer but need some guidance on the rear end. I will buy CCSB F350 single wheel, will use it as a daily driver. However, two weekends a month will go to ranch and pull '32 FT duel tandem and '32 foot livestock trailer. What is the best ratio to have good MPG daily but will handle the trailers? Thanks for any input.

The 3.31 rear end will be fine. I have 3.55 gears and am running 35" tires. I've never had a problem pulling hills and passes here in WA.

Why don't they offer 3.73's on SRW's?

They don't need the torque multiplication in the axles, with the first gear in the new transmission being so low. They reserved the 3.73's for the F350 Duallys (like they used to with the 4.10's) and the 4.30's for the F450 and aboves. The 3.33's and 3.55's on the SRW's are to aid Ford to boasting the highest fuel economy in these trucks.
