Title says it all basically

These have an all time AWD system that I’ve heard basically mimics 4 high on a traditional 4x4. It has a rear locker.

I would love to get more into overlanding as time goes on, but this is the rig I have for the moment. Don’t want to get too crazy with modding because this is an old tired girl and she’s probably got a year or two left. I feel like it is surprisingly capable given what it is but I haven’t done anything crazy.

Anybody here do anything with an AWD Yukon?
