Self-Expanding Trailer Becomes Camp Home (Apr, 1960)
Self-Expanding Trailer Becomes Camp Home
EVERY YEAR the nation’s camping-trailer manufacturers go a bit further in their contest to see which can cram the most possible living and sleeping space into the smallest folded package. A new trailer expands electrically from the neat, low-slung package in the top photo to the full size 15-foot trailer at left below. In the minute that it takes to expand itself, the inside sprouts a gas floor furnace, gas stove, sink, closet, dining area, two beds and a couch, all of which fold up or down out of the walls as the roof is raised. An interesting new feature is full glass-fiber insulation. The inventor, Leo Hagenson, won a grand championship ribbon at the Minnesota Inventor’s Congress for his work on the trailer.
