Well this is why I'm debating it, I've never actually seen a free air setup at all, let alone one in a van.
30-40 cu ft is a little high, the back of the van would be roughly 20 to 25 cu ft. MY main concern is how bad it would treat the rear doors. Recommended box sizes are 6 cu ft..... People that have experience with these things have recommended at least double that, 12 to 15.
Lazy... nah. I was thinking of doing it from a "coolness" standpoint. Cool, that is, from all my non-stereo friends and relatives. From the front all you'd see is the sub cone in the wall. But open the back, and you have the back of the sub hangin' up there with EIGHT cables (daily, reduced to four for dBDrag) running to two amplifiers... That'd look insane!
But you're right, it could sound like caa-caa. We stuck the sub in a crappy ~10cu ft box this summer, with just a slot at one end for a port... The lower ohms made my amplifiers suck about 30% more power, so everything was workin' harder... But it was 10dB quieter than my 12" H2's best score (146.6).
So....... No decisions yet. I'm still debating!
Thanks for the advice guys... keep it comin'!
