The are pics floating around of overseas Gen I SWBs with troop-style jump seats in the "way back." Hard to see that for the taller US market, as opposed to the JDM.

I've thought about it myself. Thing is, if I need that many seats, it's because I'm doign something with other people. Which means there is some sort of gear to bring as well. I would likely need a hitch mounted cargo tray to make it viable.
