We tend to associate campers with big trucks that pack serious horsepower. But what if you want to head out into the half-wilderness in your fuel-efficient little Bug? In this 1970s video, we see the answer to your eco-prayer. It's a camper made especially for what the TV announcer calls "microcars." The trailer actually attaches to the roof of the car and appears to offer 360 degrees of maneuverability. One interesting factoid: with a Beetle towing the trailer, the car operator was able to get 18-20 miles per gallon.
