This is a “for what it is worth” thought. The track that holds the slide seal leaves a little space between it and the skin of the coach. Water can collect there and migrate inside. This may be the cause.. later models started using a horizontal slit in the skin of the coach in that area to direct water away. Maybe someone with a later model could display the slit.
