Great post!  How did you tie into your propane regulator?  (Do you have a picture?) I've been meaning to set up a connection to use an old 100 pound tank I have sitting around, for when I return home and am too lazy to winterize it.  The other thing to check on, is that often getting a 100# bottle filled is amazingly cheaper per pound than anything less than that.  I think it is something like 30% cheaper so you can fill 100# for the price of 70#.  For long term use, I'd go to a 100 pounder.
Great post, great job.....nice "home" you have there!
Butch, I'm in if you get together enough people for a roll of that stuff.  I have a feeling it would be a great idea for full-timing.  We don't have much trouble with condensation, but I think full-timing we might.
