Update:
Traveled out to California last week. While on the route drove out to Sedona area of Arizona near Grand Canyon. Found some great trails while cruising the area. Found a Jeep rental location for a good rate. The jeep rental company will give me more maps and trail tips free when I go back in about a week and rent from them. The jeep is a current model Wrangler with 30" ATs for use on level 3 and 4 trails. Rules are you get stuck, you get unstuck, or you pay for a pull out. Fair enough. Sorry I cant get a Trackick but a rig is a rig when you gotta have one!
Also saw some awesome places to wheel from the west Texas I-10 route all the way through New Mexico, Arizona, Nevada, California, Including Grand Canyon area, Flagstaff area, Los Vegas area, Mohave area.
And I havent even checked out the Big Bear area yet.
Man this country is beautiful!
