33 inch cooper st maxx which regear ratio?

I just got a set of the 255/85 16 cooper discoverer st maxx and looking to regear this spring. Which ratio would be best? I live in Iowa so quite flat but I will be taking this rig to Alaska and Panama so quite a variety of terrains. Any input would be greatly appreciated.

 

I was thinking 4.10s with the 33" tires, but I'm not that experienced in it.

 

I was thinking 4.10s so I can still maintain some fuel economy. But the added weight of bumpers, drawer systems and all the expedition equipment I may need more gearing to compensate.

 

Oh yes, if you're adding that much more weight that will always be in/on the truck you may want the next gear set up from 4.10, I'm not sure what that is though, 4.56?

May want to sign up at ttora.com/ttora forums and ask there

I'm running the stock 3.73 with my 255/85 St maxx's. Only issue I have is cruise control, going up hill or over overpasses, when set to 80+mph. Cruise can't really figure out what to do, so it kicks it down a gear and seems to floor it. I've just stopped using cruise control.

 

You can calculate final drive ratios with various combinations of tires and gears and compare to stock here. http://www.grimmjeeper.com/gears.html
