HI Dexter, welcome to the forum. If you really want a teardrop trailer, you have 4 choices. You can build one, either from plans or your own design, you can buy one from the many manufacturers that can be found on this board, you can find an old relic behind a barn that has been used as a chicken coop and retore it or.........you can steal one, but I suggest you don't consider the latter.
Ah yes, Key West, I remember it well. We drove the full length of the many bridges and islands and the temps were below 30 degrees. The locals said it was a new record low. Hope you have better luck when you get there. Good luck on your build, purchase or restoration. We are here to help, just ask, and answers will be forthcoming..........

Roly, some think a Woody would be nice, but I guess I am prejudice.
