I keep my gray tanks open when I'm on an extended stay someplace. I always make a "P" trap or a dip if you will in my sewer hose near the actual sewer connection. That way I know it stays filled with water preventing sewer gases from getting into my RV. Many RV parks have their sewer connection pipes a few inches above ground level which makes a "P" trap automatically.
