Awesome thread. I'm currently thinking about "building a 4Runner" and have been looking at the Trekkers a lot. Basically what I'm looking at is taking an Xtra Cab Longbed pickup and mounting 4Runner seats in the rear, leaving the rest of the bed for cargo space. Obviously it will require a lot of sheet metal fabrication, but I figure the bed sides can be grafted to the B-pillars, and the rear window/rear cab panel can just be cut out-this is done on flatbed pickups all the time with no structural issues. Once I have thread starting privileges I'll post up some drawings.
