Am I the only one leaving in my factory floor? I love the mounting tracks that run the length of my bus, half the floor in your bus pic here. These are for securing a wheelchair, or a seat. For me, they will let me build modular units inside: stove and shelves, futon couch/bed, sink, etc, that I could just unbolt from the floor and move to another part of my bus as needs change through time, without having to drill new holes in the floor, or patch old ones. I'll be driving through the southwest in this next year, and will look for a wool rug to carpet the open floor, and make it comfortable and homey.
But then, I don't have wheel wells, either (mine's a HandyBus, with only 19" wheels). I agree, this is a gamechanger, as EVERY old vehicle I have seen, even ones that were never salted, rust around the welded seam at this location.
I hear lots of people complain about how hard it can be to get to all the bolts that hold down the seats. Cut them off at the top seems to be the way. But the floor tracks have recessed boltheads, and there are 5 times more of them than seat bolts, and you can't get to all the nuts underneath very easy.
I just started (finally!!!!!!) cleaning my factory vinyl floor with a small brush, a bottle of simple green, and old rags. Starting to look and feel nice. Then the walls, then go back over it all again with clean rags and ammonia.....kids and their boogars! EEEWOOO!
