I am thinking on picking one of these drain valves up:
http://www.fumotovalve.com/
It is apparantly approved by Nissan for use in Japan. It is a ball valve system constructed of brass & stainless steel. The N type valve is the one with the nipple which the Titan would probably take but it is unclear if the skid plate would still have to be removed. If so I would skip the idea. Anyone here have this installed on their Titan? or have any feedback?
