Logical extension though of product development from what Chrysler has 'innovated' over the past 25 years based on a concept from the 1960's.
Caravans now come with cubbies (formerly aka cabinets), cooling compartments (aka refridgeration), seats that fold flat (aka bed), television (well, not in the microbus' time, though I'm sure there was lots of 'purty-culurs' from some peoples 'recreational entertainment'
), foldaway dining tables......
The only thing left really is the pop-up roof, porta-potty and a portable stove - so is it impossible? Nope! People drive around in Wranglers and never go off road. Why not a van that has the capability to go camping?
The Sprinter would make more sense from a size perspective, but I was thinking cost-containment (my points about the VW buses and Westfalia conversions being expensive as a primary vehicle).
