This has happened to me on 2 fifth wheels. It left me scratching my head. The problem is when weight is placed near the drain, it separates the pan from the drain and leaks. I was able to spray a hardening foam from underneath to keep it from happening then I put a heavy caulk bead around the drain. When my spouse took a shower - no leak. Me, at 195 -leak.
