"... the market potential for a 4 wheel drive recreational vehicle was an unknown quantity in the early 1950s. The only such vehicle offered in the post-war period was a version of the military jeep produced for World War II. It was a flat-sided bare-bones product, and military personnel learned to appreciate its ability to maneuver over rough terrain ... In early 1958 we were directed to develop a concept to enter this small market... Our design sketches with the flat-side, no contour look never excited the executive committee. The program began to die. One night, I dashed off a rough sketch. It had contoured sides and was designed for plastic tooling. It was shown to a committee member and we were off and running."
