Right Oz.. Coming from a guy with a 10' tall truck.
..... I would like to add that you need some lift too. I am lifted 3" and spent a large part of the day on my skids and sliders at Holcomb and in some instances my front lockers were my tie breaker. But other than that I agree with Oz.
The only other thing I would suggest is make sure you have friend(s) with you that can "see the lines" and give you good spots through the rock gardens. There are good lines and very bad lines through every one of them. Pick a bad line and personally I don't care who you are or what you are driving. You had better hope you have some buddys with straps and winches around you that can help.
But all I can say OZ is I really need to see your rig work tomorrow...
