I have the selectable in the rear much better than the auto in the rear. I run an Aussie in the front you cant feel it on the street due to the ADD disconnect. Off-road it works great I have yet to run into an issue with driving. I haven't run into any steering issues or extra breakage I haven't really changed my wheeling style I don't beat on it but I also don't baby it. As long as you don't do something stupid like put 37's on it then revlimiter assault a ledge.
If I ever make it to another TW wheeling trip you can take mine for a spin to test it out.
