Thx guys, there are lots of answers to my question, if I had 5-6k to spend.
Those Yurts were cool, but a quick price check and over 5k.
Our land belongs to a timber company, don't think they would appreciate me cutting down that many trees, and wouldn't know how to build a log cabin from scratch.
The pre-fab stuff that I have seen usually has 6ft high walls, I wanted ~8ft walls so that the guy(my son) in the upper bunk could actually sit up.
I've looked for campers, seems most people think they are worth their weight in gold, I always do keep my eyes open for a deal since that is the simplest solution.
My pop-up would probably sell for $500-1000, so that would be my base budget. If I could build a dried in shell for that money, I could pretty it up and make it more plush (wiring, plumbing etc...) over time.
I've seen some web sites for homes that are 'off-the-grid', there are some great ideas, but everything seems a bit too expensive for a hunting cabin.
Thx again guys,
