RJ,
I did some searching on it and found out that it's a TradeWind. The shell
is 21 to 22 feet long. The Serial # is 249118. Looks like it had a few
mods done to it over the years. Mostly with wiring and plumping hook ups
being moved. As to the year of the Airstream I haven't found anything
dated on it yet but I'm going by what the owner said.
