Hmm, I'm sure I can find some pics of my various rigs being stuck at one time or another.
Moab, UT: high centered on some rocks that decided to shift and get lodged under my rear diff (and I had no lockers in the X):
Took lifting each tire with a hi-lift and stacking rocks under them. By the time we finished, there was quite a line of rigs waiting to get by. Ooops. :-/
Recurring theme- open diffs make for interesting experiences on obstacles.
Axles are crossed up on Silver Crack @Moab, no traction or momentum with 2 tires in the air:
Bunch of guys had to climb on the rear to drop my rear tire and get some traction:
Mud is evil. So is wet loam/clay or anything of such nature.
Sold the X. Got a Rubi. Thank goodness for winches. Was driving home from a friend's house in the mountains. My typical route home was closed for an event and the next one was snowed in still (it is May). Continued heading for the next route and got bogged down in an embankment of snow. Had to winch myself out and turn around and go all the way back. Gotta love being by yourself, at dusk with intermittent cell service. *sigh*
(I already started winching myself out. Snow was all the way on top of my front tire/bumper.)
Probably the most stressful save. Friend's X hit soft dirt that started to crumble under him leading to a cliff side. He could not go forward or back. I had to drive up on a ridge line (stack rocks to drive over a pipeline to get there) and hook winch up to hold friend up while a second winch pulled him from behind. 4h later we got him free.
There are more, but those are the ones I found most easily.
