1960's California-think would have a few friends go in together to rent an Airstream/Argossy/Casita etc. travel trailer for a week,then take it to someone's shop where they could make a plaster splash of all the compound-curved parts from which they could create fiberglass reproductions for their own projects.
At week's end,pull off all the protective barrier films and return the T.T.,telling what a wonderful trip they'd had.
