Terrific pics guys.  You are a great group and I promise not to miss the next one.  I wish I could add those  pics to my Joshua Tree Google file, but I would need approx coordinates for each pic.
I was gonna go on this trip, but a few days before I was reinstalling the air line to my front ARB locker.  It is a brass threaded connector into the front diff, and I overtightened it and broke it off... inside the case.  So I dremeled out the busted connector and in so doing carved a nice hole in the case for oil to shoot out.
Spent the next day degreasing around the whole area, then reinstalled the locker line with globs of JB weld.  So far it has held on.
