Was planning to just insert small patches into floor to repair some water damage but once I removed the couch (what a pain!) and went at the wood with a wire brush to see how far the damage extended I find I'm in for some real work. Front riser floor needs to be totally replaced
I do have some questions from those that have been down this road before.
What is the best approach people have found for removing the screws going into the frame through the floor? Pretty darn sure they won't turn. Have been thinking of just grinding them off with a 4 inch grinder. If someone has a better approach would love to hear it.
How have people supported the shell when replacing this portion of the floor? Especially when tabbing it in to keep it at the right height. Was thinking of using boards as posts to prop the roof up, or maybe jack stands and boards under the shell.
What made this job a pain. Even using a hand impact driver I ended up snapping a screw head off, having to drill one head off, and cut another off with a dremal. But the real pain was the 6 rivets that come through from inside the kitchen cabinet on the couch street side. Hard enough to drill out a rivet from the blind side since the drill wants to slide off of the center shaft but doing it by reaching through the couch storage made it really hard to get in a good position and control the tools. Back of my arm is covered in gouges from the edges of the access to that storage area. Getting my head in so I could see and my arm so I could work.... PITA!
Street side. If you look along the side of the cabinet on the left you can see where the rivets were. Also note the wood "shelf" that should be there to support the couch along wall is missing (rotted and removed I guess)
On the curb side the wood did not look bad but was soft (just covered in paint) Little digging and it turned out to be no better than the other spot. One odd thing about the shelf lip that the couch screws into on this side were it still has one. It's 3 ply for part of it near the door, 5 ply for part of it toward the front.
Thought it worth pointing out that the vertical surfaces that form this riser are steel, part of the frame. And you can see the shelf to support couch just ends about where the water leak tracks are going down the wall, was removed by previous owner (probably with a shop vac it was so rotted). Also the tracks from the water leak are easily seen. I suspect it was stored leaning toward the door and what did not go out the propane
line hole travelled around to the far side next to the door.
