A friend of mine flipped his jeep over in a mud bog about 4 or 5 years ago.
Luckily his wife and kids wern't riding with him that day and very lucky for him that he didn't panic and remembered that there would be some air trapped at the floorboard so he could get a few breaths before trying to get out of the thick mud.
All that was sticking out of the mud were about 3/4 of the tires.
We now call him snorkle.
Any Jeep ride you can walk away from is a good ride.
