Installed the overflow on the gray water tank. Simply a few PVC connectors with on top a small piece of window screen material, held in place with a clamp.
Next will be the 12V electric valve, A switch at the steering wheel will allow me to open the valve and dump the content of the gray water tank at a dump station.
