Thanks for the offer man, but don't sweat it. I actually just took everything out of the back of my jeep and snapped a few pics of the damage to add to the review.
I'll probably just order a replacement from mcmaster and get some more pliable rubber for the fridged temps.
Other than that, the only other thing I didn't like about the xjack was having to hook up the exhaust hose. It'd be better if there was just a plug or something to use when inflating with a compressor.... but then again, if it was a nice warm day it probably would have also been a non-factor. With frozen hands, every second matters! lol
