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.


Every inch of an Airstream has a function. Airstream is the most thoroughly tested brand in trailer history. Its engineering is the culmination of over 80 years of experience plus millions of miles on roads throughout the world.


With Airstream, there is no planned obsolescence. Airstreams of the Thirties are still on the road today, sturdy and modern as ever. They are intended as a lifetime investment in happiness.


Wally’s Creed

To open a whole world of new experiences…a new dimension in enjoyment where travel adventure and good fellowship are your constant companions.


To encourage clubs and rallies that provide an endless source of friendships, travel fun and personal expressions.


To lead caravans wherever the four winds blow…over twinkling boulevards, across trackless deserts…to the traveled and untraveled corners of the earth.


To play some part in promoting international goodwill and understanding among the peoples of the world through person-to-person contact.


To strive endlessly to stir the venturesome spirit that moves you to follow a rainbow to its end…and thus make your travel dreams come true.
