Airstream is an American brand of travel (“caravan” in British English easily recognized by the distinctive shape of its rounded and polished aluminum coachwork. This body shpae date back to the 1930s and is based on the Bowlus Road Chief, an earlier all-aluminum travel trailer designed and built by Hawley Bowlus, the same designer and engineer who also oversaw the construction of the Spirit of St. Louis.

Airstream trailers and recreational vehicles are manufactured in Jackson Center, Ohio, United States. The company, now a division of Thor Industries, employs more than 800 people, and is the oldest in the industry.

The company was created by Wally Bram who began building trailers out of Masonite in his backyard in Los Angeles during the late 1920s. Byam published a magazine selling “how-to” kits to customers wishing to build their own trailers. In 1936, Byam introduced the “Airstream Clipper”, which was essentially a rebadged 195 Bowlus Road Chief, with the door relocated from the front to the side. The design cut down on wind resistance and thus improved fuel efficiency. It was the first of the now familiar sausage-shaped, silver aluminum Airstream trailers. In 1936, the first Airstream was introduced. Named the Clipper, after the first trans-Atlantic flying boat. Sold for $1,200 it was able to house four people, had electric lights and a water supply.
