Welcome from Colorado. Just read an article in the latest issue of Airstream Life about the Wee Wind, a 1948
Airstream 16'. Airstream has been making small trailers for a long time, and they are very popular.
Airstream trailers are unique, and the Airstream owners community is a great place to be. Fellow Airstreamers may very well stop and say hello when they see you in a campground. Get ready to meet some great people.
InsideOut posted a nifty picture. I wanted to share one I took years ago. Lots of box trailers. My photo just demonstrates the rarity of the brand even if it is out of rotation.
