That trip to rubicon and Moab looks strangely familiar... Bet there is a thread on here with lots of info and talk ;D
I still plan to do it but it will be probably 2012 for me before I got the funds and jeep capable of doing it. Not sure a tow rig is in my future so for now I got to build for trail and long distance DD.
Before doing all that driving in the Jeep, I would consider shipping it (almost same as fuel costs) to Denver, fly in, do Moab and then drive to the Rubicon, and then ship it back from Lake Tahoe, and fly home.
By the way, our roads in GA are AWESOME. Some of the roads on the North and South routes SUCK.
