Need help identifying where water is entering my 2013 Airstream Interstate Lounge. The interior wall on the driver's side is wet next to the seat and down to the floor behind the couch in the rear lounge. The wet wall begins six inches below the side window and at the top of the exterior opening for the hot water heater. There is a small amount of water on the van floor between the wheel well and the rear of the van.
I dried the wall and the floor but have been unable to identify where the water is coming in. Used a garden hose to spraying around the hot water heater, magnetic door knob, side window, and roof. Anyone have a leak in this area and identified the source?
