I'm starting to like that idea too BobHenry, but I'm worried about weight.
I still need to know what materials I should use. Pressure treated or not. CPES or roofing tar? What's going to protect the bottom frame the best?
Also, how much clearance should I give that "basement"?
These are things I need to know before I start the build.
One other thought. I was looking at some pictures and I noticed a camper hooked up to a camp site and there were three lines from the pole to the camper.
What hook-ups are usually provided at camp sites?
