Brooks Stevens' FC Jeep Van is correct!
Welcome to the Pro ranks, Hugo!
The six-door commuter van was based on Jeep's FC (forward control) truck line. Three prototypes were built, but production was never green-lighted. Unlike the forward control VW vans and trucks that were introduced a few years earlier, these were rugged work trucks, with up to 5000 lb towing capacity, 4 wheel drive, and a tiny 18 foot turning radius. Detroit introduced similar forward control trucks in the early sixties, but without 4WD.
