There are 2 problems with silicone. 1. It will break down and fail to seal anymore. 2. Once you've applied silicone caulking, nothing, not even more silicone caulking will adhere to it so you'll never get it sealed again.
I have direct experience with both of these. It's a long and very frustrating story that I won't go into very much. On my popup, years ago, I sealed a couple of joints with silicone. I tore my hair out for many years trying to deal with the consequences. I'll never use silicone in an RV again.
