I've watched hours of video of FJ40s on the Dusy-Ershim trail. There was only one rig in the group on less than a 35" tire with a spring under suspension set up, and he put was banging and dragging his rocker protection all the way down the trail. This is not to say that you wouldn't be fine as driver skill has everything to do with rig capability. Justice and Carlos are GREAT drivers and spotters, so I'm sure they'll be a great voice of reason to let you know what you should and shouldn't do.

I wish I was going, too...
