condenastion or leak in corners?????

Were your windows wet as well? We used to get a lot of condensation in the winter when running the heat. If you cook inside your coach, you are adding more moisture into the air. Once we got a dehumidifier, no more issues. When you get home, a simple run over the area with a water hose will let you know if you have a actual leak (be careful not to over wet if possible)
