This vehicle is marketed elsewhere as a family oriented recreation vehicle...hence the rear seats and windows presumably. In this guise towing is a pre-requisite I would have thought. So that thought might have been put into this mode as a development of the product. Anyway, for small trailers there is not much out there that fits the bill very well if you discount pick-ups, SUVs and ordinary cars. Internal vehicle stowage is required to cary some stuff. The Caravan does a decent job but is a little long.
Commercial users would probably not need this ability.
