This book is a great overview of the history and variety of travel trailers out on the road. Great quality pictures of all types of trailers, trailer parks and vintage ads. Finally, an un-biased history of the trailer, which tells the real story of how the Airstream came into being. The inventor of the aluminum aircraft-style trailer finally gets his due (hint: Wally Byam didn't invent it, he just perfected it and marketed it better). Also a great source of ideas for those lost souls who undertake a restoration of these beauties. Americana never looked so beautiful and interesting.
