Next year I'll be working and won't be able to get the time off. And I haven't. But I'll look into it as it's near the area I live in
Understand the work and getting time off thing for sure. With that in mind you need to find a group to travel with that can help make your trip a success.
If you have body protection then I'd really work towards a 4.70 t-case ahead of even lockers. The control you get is fantastic. The most likely thing to break on the rocks is your front axles and that results from impact loading from bouncing and hopping. I did several weeks in Moab on the difficult trails with stock front axles but I very intentionally never went past a Detroit TrueTrac limited slip in the front until I got upgraded front axles. As long as you have some support and are willing to use it, you can make the trip work.
As far as Nanches Pass, I was just trying to find something in common that we have both wheeled to get an idea of how difficult you thought it was in your setup.
