Took my Jeep on some easy to moderate trails nearby (70 miles from where I live) this past weekend. I am happy to say that the Jeep performed great and exceeded my expectations. I had to use 4-Lo in some sections (I made some wrong turns on the trails) where it was a very rocky.
My Jeep is stock except for the wheels and 32" tires (Dueler AT) from a 2012 JKU. There were some very steep sections with ton of rocks and I used the 4-Lo (plus Hill Descent Control when coming down). The Jeep did these sections really really well.
Here are few pictures.
This is what happens if you do not pay attention.
The below picture is what's on the other side of the ridge.
