My 2008 FF 18FBR bathroom leaks. We pulled out the shower permanently because water had gotten behind it and destroyed the wall.That was last year. Dried the wall out took out damaged beyond repair wall chunks and repaired. There are no outside obvious leaks but my back wall is still wet. Suggestions??? The leak is in the back corner by the outside corner. It is currently disconnected from a water source and has been weatherized. I am trying to bring it back so I can go camping once COVID restrictions are raised.
