Have bought a new 2002 HR Vacationer 34 PBD and have found the floor wet several times. Seems to be coming from under sink area; saw water coming out from under the cabinet. What is crazy we looked in cabinet and floor was dry. We rebalanced coach to make water run to outside of coach. Dealer has searched for leak from water heater, sink connection and around door and window and the roof. No luck. Water seems to come after a rain. Any quesses on where this unit is leaking? We are at a loss.
