Hey Ed,
Glad to see that you found this group. It was really great to see you at GoneMoab and if I can schedule the time I may try to get to the Rubicon one more time with you guys. I would suggest though that you provide them with minimum requirements for the rigs, i.e. lockers, winch, sliders, skids, spare tire(s), recovery equipment, etc.
Just to add (And all can take this with a grain of salt) I wrote a little article about preparedness for the GoneMoab event. Anybody that intends to do the Rubicon Trail might want to review this and see if there is anything you might want to take along.
Thanks Ed for thinking of your fellow four wheelers.
