well to answer the question, no i have not rolled one. but i came damn close on my first real trip with my jeep a few weeks ago in LI..45 seconds into the trail i fell into a hole and listed the jeep real bad..teetered at an angle at was way too far over for my own comfort. had two of my friends hanging off the side and a strap on the roll bar while we tried winching me out..to make matters worse, she kept wanting to roll over as the winch pulled....50 min of tiresome digging under the driverside wheels helped rectify my situation and i got pulled out without a scratch. not a bad introduction to the world of jeeping
