New Class A - Water Entry

Yes, the water can come from your holding tanks over flowing, if the basement bays are attached to the main body of the coach and do not move out with a slide room. You should be able to tell from the type of water you had to dry up. Do not let your holding tanks get too full. It does not take much over flow leakage to seem like a lot and make a mess. If you dry up the bays, and don't let your tanks get too full and you still have the issue, you need to talk to your dealer.

Good luck-- Mick
