So how am I supposed to know when the fresh water tank is full. There is a large warning sticker on the side that says do not leave the water unattended while filling or you could cause serious damage by over filling. So here I am waiting for a overflow tube to tell me the tank is full. But NO water starts coming out from all sides of the coroplas. Is this what tells you that the tank is full. Crawled under to check the coroplas drooping as expected punched a couple of holes for drainage. Dripped water for three days. So what damage can I except from this overfilling. I am taking the coach to the dealer for repairs and want to know what to have them check for such as ruined insulation or other problems that I am sure you are aware of from the posting of the large warning sticker.

Thats another story.
