I'm still fairly seriously considering this. I've watched a few videos of several vehicles doing this trail and while I don't think I can do all the obstacles on their hardest lines I think I may be able to do the easier routes. It would be nice to actually use the winch a bit and get some practice doing so with spotters and good advice from experienced members.
I may also do like James suggests and just go for the ride/hike along the first time.
For me to go I'll need to spend some time under the Jeep, getting all systems 100%, and take a long hard look at my trail tools and make some improvements there, JiC SHTF.
