Can't help you with a specific boondocking location. Just wanted to reiterate the need to be prepared. Lots of water and food, extra spare, air pump, jacks, etc. And make sure your rig is ready for very rough terrain. Last time I was in there (years ago), we passed several jeeps with obvious fresh body damage. Running boards are just there to get torn off. Was no cell service anywhere. Definitely a remote part of the world.
