The Stovebolt Site Forums The Shop Area General Truck Talk Hole in floor under seat

I have a round hole in the center underneath my seat; and in my case that area is sloped inwards (like a drain). When I was prepping for the floor repairs I power washed the interior and I can state with certainty that it works effectively like a drain, although why you would need one under there I'm not sure. I put a rubber plug in mine (they had the right size at NAPA).

Picture shows where it is but doesn't do the slopes justice, IIRC it's about a 1/2" hole.
