Must Have Boondocking Items?

This Thread is a wonderful exercise in prepping and survival. We have listed general and personal boondocking preferences. I have gotten several good ideas, and I hope have shared some good info as well. I decided that the whole concept of boondocking is to be free from, and independent of, the need of support while at your destination. The only limitation to any stay is the time between restocking, and mandatory maintenance. Water, food, fuel, and holding tanks, the basic 4. So the time spent on your own is dictated by how many people and how far the destination is from the last chance for service. As a gold miner I do several solo runs. My little 24' 79 Class C will take me there for a week and bring me back from any destination in a 3 hr., one way drive distance. I have a mining outing Friday 04/26 for 2 days. I'm bringing 65 gal. of extra water, over the 40 gal in the Fresh tank. I unload it at the camp site when I get there. I don't have a shower in the coach yet so I bathe outside with that water. It is mostly for mining though. I run a desert mining wash plant.
I use a dry washer for most of my mining, but the last step always needs water, plus it's good to have utility water in the desert. This is a boondock outing with anywhere from 20 to 100+ miners. It's a big and rich club owned gold claim out near Red Rock Canyon CA. It's at least 30 miles from any public services. Even cel phones don't work.
I love it. Best club I ever joined.
