Idea: Modify the carport

I was thinking that the carport may be overbuilt a bit.  You can make something of a permanent structure, but also have the quality of being taken down when not in use---like a teepee.

The system I am thinking of would require some post holes, as in the carport idea, but no permanent roof.  Thus, there's no roof, no walls, and no floor.  Everything else would be carried along on each trip out there.  You'd place that stuff on top of the permanent structure, which would be something like a skeleton.

A tarp would serve as a roof.  Also, tarps could serve as walls for protection from the wind.  It would not be fully enclosed.  Instead, the van would drive into it like a carport.  The van would be like an RV.  You could live in it for a few days, or perhaps a couple weeks.

The system would have to be robust, but not have to be built like the Taj Mahal.
