The Playpac, invented by Steven Whysel, was the answer to the needs of the growing horde of VW "Bug" and other small-car owners who wanted a hard-shelled camper, light enough to be pulled by a small car. It came with a private water closet, shower, and the ability to sleep six. Its ultramodern aerodynamic styling and domed skylight by the modernist industrial designer Toshihiko Sakow made it an instant hit. It was short-lived, however (1971–1973), as the first Arab Oil Embargo and the ensuing major slow-down of RV sales caused it to cease operations. The Boler travel trailer, was developed in Canada in 1968, soon joined the Playpac in the U.S. fiberglass light-weight class. The Hunter and Amerigo travel trailers were also on the scene by then.
