Theres no real practical way of describing how exactly airstream trailers are constructed including every single step... BUT i did find the official factory tour and they walk you through how an airstream trailer is made AND they include pictures! If you are serious about learning exactly how they are constructed follow this link to the official site: http://www.airstream.com/product_line/factory_tour/factory.html Heres a little excerpt: Shell Assembly To continue the tour, I'd like to show you how shell assemblies are made. Let's start with the floor. Airstream floors are made from 5/8" tongue and groove or OSB flooring . Right now Richard is fastening aluminum channels to the floor and shell assembly. Richard has worked here for over 19 years and really knows what he is doing. Brad makes sure that the slots in the channels embrace and protect the edge of the wood floor — providing weatherproofing and strengthen the area where the floor and shell are joined. assemblies5 Assemblies The classic trailer shell is constructed of five separate assemblies: the roadside and curbside side sheet assemblies, the front and rear end assemblies, and the roof assembly. The assemblies are attached with aluminum aircraft rivets on a steel fixture. Then thermal barrier bonding tape is used to create a thermal break between the ribs and the aluminum sheets. This helps control condensation and the transfer of heat or cold from the outside environment. trimming segmentsShell Stretch Forming The end shell segments are stretch formed on a mold for each segment, trimmed and punched for assembly.

Soft, flat sheets of aluminum are stretched into the signature shape. Thousands of rivets fasten the aluminum sections together to form a shell. The shell is attached to the chassis, tested, wiring installed, walls insulated and finished. Ratz's Facts: Over sixty-five percent of all Airstream trailers ever built are still on the road today. Price is between $25,000-$75,000. The average airstream owner uses the trailer 28 weeks out of the year.

I posted a video on youtube that shows exactly how the Airstream travel trailer are made. http://www.youtube.com/watch?v=sB4llenpCf8
