Has anyone looked into doing this before? I haven't been on the forum all that long, so I dunno if anyone ever tried to set up a large area for campers. I've lived on a rez. I'm a tribal sort of person, but I don't think the average American is ready for tribal life.
You might not like it as much as you think for long term. You still need a governing body, which in this case is the owner of the land. You'd have to be okay with his rules. The thing that is different is you all aren't related to each other. In the native sense, we're related to each other. We have a vested interest in the well being of everyone in the group. Social stuff is important because it binds people together. This is not (generally speaking) the mindset of most I've met out there. I mean the first thought people have is, I'd like to own/rent my own small part of the acreage and cordon off my part...not that they are looking forward to sharing the land and the labors of the land.
And the other thing is among real tribal people, the one who gives the most away is the wealthiest person, not the person who has all the newest gadgets, satellite dishes, super bandwidth on 7 different wifi servers, solar covering every square inch of the roof so he/she can have a/c and mega possessions crammed into a six or seven figure RV. I hate to be a downer in this, but I'm not sure the people I've met in this lifestyle are really tribal material.
I roll my eyes sometimes when people call others in this lifestyle a "tribe" because this is not a tribe. It might be a movement, but not in any sense a tribe. Most I've met are rugged individualists, and that's great, but they don't make good tribal members. Loners, introverts and egocentric folks don't work out well either. Generally and ideally speaking, tribal people live with the good of the group as a whole in mind.
So if you're setting things up, it might be easier and work better to just set yourself up a normal campground where people just pay to stay and be on their way when they're done staying like any other campground. I suppose you could make the cost low so that it would be do-able to those with limited means. You could even make the cost of staying on donations. Put up a secure box and people can drop in whatever they can afford.
At any rate, good luck with your endeavor.
