Water in the belly
In my case it was two problems..in the first forest river did a poor assembly job and the circular pvc rub disc did not prevent the wooden hole in the kit sink cabinet from rubbing a hole in the water line...
Second case. One of the water lines from water heater to bAthroom was poorly routed by forest river when they forced the water line to bend through a hole instead of using elbows...I could not believe it. How cheap! The line split
Both cases filled the belly with water..a friend and I fixed both leaks..from did pay us for the materials but what this says about grey wolf construction I don't know
Y o u will need a flashlight and mirror to discover the source of the leak. Fortunately the belly can be cut open,repaired,allowed to dry,and resealed if needed
