I'll put my money on them NOT flipping it. If you take a look at the motor, it appears as though it's mounted a bit lower than the stock setup. The weight can also be spread out better now that the drivetrain is rwd.

With the correct suspension setup and a few changes in weight distribution, the Elephant ain't rolling over any time soon.

I have yet to roll my Cherokee and I don't have anything other than stock suspension on there. Sure, I've scared the piss out of myself and passengers, but it has never been on less than one wheel (yeah, that's the time I was scared.
