This was a video I took while on a run two weekend ago's with the Yuma4wheelers. The driver of the Jeep was very lucky in that his Jeep didn't go over as it would've been a pain to flip him back over due to the area that he was in and he stuck his arm out the window.
In another video from the opposite you can see that the Jeep is balanced but any more and it would've went over.

Here's a FJ40 and a Toyota/Jeep Hybrid in the same area making it look easy.
