They attached the sides HOW?
Hello, I have a Toyota Dolphin 20' RV. It had been stored by the ocean for many years before I bought it. There's a big hole in the floor, and basically the entire floor needs to be replaced. ...

Do not use silicone caulk. It doesn't hold up well in RV use. It will look like it's still working, but can be leaking. And when it's time to re-caulk, it won't stick to itself. And nothing else will either.
If you are caulking anything on a rubber roof, use Dicor self leveling lap sealant. For caulking on the aluminum, use ProFlex RV, or equivalent Sikaflex or OSI Quad. Underneath corner trims, window flanges, roof vents, and other mounting flanges, use high quality butyl tape. Usually it will be medium gray, and it's almost bubble-gum like in texture. Not the drier putty tape. I've used a lot of the putty tape, it's okay, but the butyl tape is a lot better.
On any window or other sidewall penetration, after you install it with the butyl tape, then drape the top and side edges of the joint with Proflex. On a roof, you drizzle the Dicor over any finished joint or flange, and don't skimp on it.
repeat after me: No silicone!
