Sorry I didn't see your post before! I did the complete route, and your GPS tracks were indispensable! I'm sure there would've been many miles of backtracking using just the books and the addendums. I skipped only one of the "hard" sections as stated in Post #14. Post #19 mentions skipping a section to get to a campsite, but I completed that section 2 months later on my way to DV. I guess it was relatively uneventful, as I didn't augment this trip report to show that I did that section!
I drove by mailbox 2 without seeing it, and that night my companion (Driller) said "yeah, you drove right past it!" I checked in to all the other mailboxes.
I don't do insta. There is 1 one segment that cannot be travelled by Carbonate King Mine, as someone drug boulders across the road and installed "Private" signs. It's on your GPS track # 0041, and here are the waypoints of the Private signs at each end of the private land:
West side private sign 35.42631, -115.50368
East side private sign 35.42844, -115.49816
