We had the Extend A Shower in our previous trailer, one of the best mods I ever did. Loved it, and as a bonus, you can hang damp towels over it. We replaced curtain that rolled with wheels on a track attached to the ceiling. I filled the holes that were left when i removed the track with some white bathroom caulk and you would have to look very close to find them. As to the mounting hardware, I don't recall exactly but used the supplied hardware. I did not seal the screws as it really did not get wet up there, but it won't hurt to do so.
