I tend to agree with the 4.10 or 4.11 , whatever you want to call it would be good for an application like that. Nobody has mentioned reverse. Turning around in the woods or backing up to a dock the lower gears are much easier on the truck in general. I was just reminded of this tonight when I backed a friends 3.36 truck into a chute that has a slight uphill approach. Specced same as my truck except I have 3.70's.
