1976 at the Dutch Motorcycle Ed Pols of Moturist sidecars presented a sidecar that transformed into a folding camper in around two minutes. Complete with draw-out kitchen and double bed, the sidecar weighed 120 kg. It was offered at a cost of a whopping $1750..a lot of money for the time. The concept never saw production, and only the prototype remains..safe with a collector in Holland.
