Jwireman89 has a great suggestion. I have found that some campground sewer systems siphon the drainwater from traps. I think making a loop drop of sewer hose could help minimize the siphoning. We experience the dreaded sewer odor probably once a year. Closing off grey valve always corrects. Often just running water in all drains eleviates issue. Because this happens randomly and we haven't changed our practices I attribute the occurances to campground drain systems sucking our drains dry.
