Airstream RV Logo

In 1931, Airstream began with Wally Byam’s dream: to build a travel trailer that would move like a stream of air, be light enough to be towed by a car, and create first-class accommodations anywhere.


Wally Byam introduced the first riveted aluminum, semi-monocoque Airstream – known as the Clipper – in 1936. He forever changed the world of travel and built a community of like-minded adventurers called Airstreamers. Today, the entire Airstream community keeps Wally’s spirit alive and well.


Airstream travel trailers and touring coaches aren’t built the fastest way. Not the easiest, either. That’s because they’re built with an obsessive attention to detail, and a willingness to choose the processes and materials that make the absolute best product – even if it’s a little harder, takes a little longer, and costs a little more to do. That’s the kind of quality that makes Airstreams last not just years but generations, and the kind we’re proud to put our name on.
