2015 - 2018 Newmar would get water in the space under floor of the bays.The water would get pick up by the tires in the rain and spray on the bottem of the floor and then run down the frame of the coach to the under belly of the coach the bottem under the bays floor. Then as you drive the water would get spalashed on the OSB WOOD (NOT PLYWOOD) and make it rot.
Newmar cut the bottem off our 2016 DS 4 times. Becouse it would hold 100 GAL of water under the bay floor beflore it would start leaking out.
Newmar now has put low point drains on the bottem of the skin of there coachs and use a new leak check system to try to stop the water leaks from the outside in.
AS a side note do NOT store you coach with a full tank of water it will sweat like a glass of ice tea on a hot summer day.
Recommendatation replace floor under tank with marine plywood NOT OSB.
