RV FLOODED - Make Sure You Know This About Your RV

[@77yorkiegirl]

Can I ask why my earlier 2000's wildwood fifth wheel camper would have completely filled the bathtub by itself, obviously by backing up through the drain, however I never use it, the gray tank has been empty for almost 4 days, I don't shower here because I don't have hot water. I barely use gray water in three months. But it is also in the floor vents! The heating ducks on the floor have several inches of water and the entire entry area, steps and vanity/bathroom area are completely soaked that there's over an inch of water in the carpet! Do you know what could possibly be causing this? There's not a leak in the roof or anything that would've done this, and we just replumbed it three months ago with pipe and fittings! Don't understand.
