By definition, a chassis is any supporting frame or structure, usually for a vehicle. For Airstream travel trailers, we use the term in reference to the steel ladder frames that create a solid foundation for the trailer to be built upon.
To complete the chassis, Airstream takes the steel frame and installs the holding tanks, wheels, shock absorbers, stabilizer jacks, and spare tire.
Then the initial plumbing, wiring, vent lines, hitch jack, and step are installed. Sensors and insulation are installed before the aluminum trailer shell is lifted and installed onto the completed chassis.
You see more about the chassis and how it's used in our factory tour video.
