Has it ever been done? I think it would be particularly awesome in a wagon where you really need to fill that big cabin with some cold (or hot) air.

Is there enough room in the tunnel to do this? I was thinking about just adding the rear vents to the tunnel with a duct to the main system and an additional 12v fan to be triggered on w/ the main blower. Could be cool, right?
