How will the new 2011 Grand Cherokee with air lift system do in Moab?

I'm looking for a family truck that will be able to handle some challenging trails in Moab as well.  Any thoughts on the 2011 GC?  

Well, I test drove a lot of stuff.  I considered just keeping our Suburban as our Motorhome tow vehicle, and getting something sporty but with decent ground clearance for snow here in Utah, like the Infinity FX35.  In the end, I decided to order the 2011 Jeep Grand Cherokee.  My brother had a GC in the 1990s, and I always thought it drove and road like crap on the roads.  I swore I would never own one.  Well, the 2011 GC is very different.  It drives surpisingly well, looks great, nice interior, lots or rear seat leg room, great towing capability for its class, and can get me just about anywhere when we go hiking in Southern Utah.  I decided that on days when I want to go more crazy and try "Hells Revenge" I'll rent a jeep for $150 instead of risking denting the doors, etc, on my new car.  The bummer is I have to wait 2-3 months for my car to be built.  Hopefully I'll get a better idea on a build date next week.  I got the Overland, Mineral grey with Saddle color leather, with every option, for $47,000.  Not bad considering the Acuras, Infinities, etc, which can't get out of a mud puddle, cost even more.
