biglarry...First of all..I would like to give you some "Monaco karma" if that is OK?
You will find everyone here willing to help as best they can...so always feel free to ask questions...or even throw in some of your own comments & ideas!
I believe that they are like any rubber seal...they need to be replaced periodically.
How old is your coach...would it be time to replace them yet?
Again...welcome to iRV2 and hopefully the Monaco forum.
We hope you visit & post often.
