I can somewhat understand why John is doing some of what he is doing. He wants space(open floor plan) so he is taking out everything. Some of which I myself would leave, but his choice. As far as the money goes, I understand that part too. He may not have X amount of coin to throw at it at one time, but over time, he buy some here, some there. I get it.
Bottom line, I think he still wants to camp, but wants a dryer, easier to heat and cool place to have, more so than a tent.
I am assuming he will do his cooking and so on outside, just as if he was tent camping.So I will keep my opinions to myself, not what I would do, but, seems he is pretty much doing what he wants.
Keep pics coming on progress.
