Real world experience, as of yesterday. Rolling down a soft dirt two-track at under 5mph, the right front wheel of my Dodge 2500 fell into a hole. Truck was resting on the front axle and skid plate, with the wheel and tire hanging in mid-air, about three feet above anything solid. Locked up both diffs and tried to back out, just dug three holes in the dirt. No good way to lift the front with a Hi-Lift, so I got out the ARB X-Jack (carried for years but never used for real). Plan was to raise the wheel high enough to bridge the hole with my MaxTrax, and then just back out. Got the X-Jack under a skid plate and started pumping it up with my OBA. X-Jack raised the truck about 6", then blew a seam and dropped the truck back into the hole with a bang. So, rather than call for assistance, I dug out behind the rear tires and wedged two of my MaxTrax under the rear tires and backed out slowly in low range with the diff locked. Thirty seconds of throttle modulation and I was out. Bought the MaxTrax for this kind of situation and they have now paid for themselves. I am a believer.
Now I have to call ARB and ask about this blown seam problem. Same issue came up in user feedback on Amazon, so not an unknown failure mode.
