No no no, your going about this all wrong. The 4runner was designed with the crew served weapon in mind. The MPAV is all ready and set up for use of the XM214 mini gun or even a .50 Cal. The location toyota considered was the sunroof as it has great coverage but is limited to the room a person has to move with in the cab (stepping on the drivers head and all ). They decided to modify the rear cargo area for such uses. Now think, a nice open area to sit, cargo compartments that can be fitted for incoming ammo and ammo dispersal. Lets not for get the greatest R&D idea Toyota had, it was the auto open rear window (awesome music plays when its being rolled down and a muzzle appears only 10 feet from oncoming zombies). Shrockworks provides the front protection and possible flamethrower mounts to replace the fog lights. Just my 2cents.
