Around here I have yet to get stuck on 33 ATs, 3.5" (measured, not advertised, and that was before my 100+ pound bumper) in the front and 4.5" in the back (measured, after adding 2" HD springs, 1.5" boomerang shackles, and a lot of bouncing it off things, towing, and stuff hauling) except in front of a crowd at the great american jeep rally... and that was because I planted my front diff solidly into a rock when I didn't quite make a turn I meant to.
I have made it through things that people told me I had no business trying (though they thought I cared about the sheetmetal. I have zero problems dragging sheetmetal over things if it means I make my line, and the rig is starting to show it.)
I haven't wheeled it much (only 4-5 runs) since it was stock, only a couple trips, but will be fixing that.
