Look at Talin RV in Florida. He is a Monaco owner and owner of Talin RV, he created a system called guardian plate for the Monaco’s that do this. Which is pretty much all of us original (2009 and earlier ) as there was a design flaw that allows water intrusion in our slides.
at the Monacoers gathering this past week he gave a seminar on it. They are a great source of info regarding the issue abs ensuring you fix it not just patch it
