Ahh, Shastas are great! So are Airstreams, Avions, Spartons, really, I love them all. I really like all the canned ham style trailers though.
Currently, I have a tiny tent trailer, from '72. Its great, in that it weighs nothing, and you can't tell its there. Plus, I can tow it with my car. Plus, it was free.
I like the idea of a teardrop, but it is nice to have somewhere to get out of the rain, bugs, etc. Anything that gets you out there though. I, like everyone else, would like a Bambi, but certainly cannot afford it!
Neilroy, if you go ahead and use that cedar inside, and are worried about the smell, which I doubt would be overpowering after a few months, you can finnish it with a couple coats of shellac. This will stop the smell. On top of the shellac, you will need to use a real varnish though, not a urethane, as there are problems with adhesion.
