I rarely get to use Full Hookups. I knew to leave the Black Tank drain closed, but thought I could leave the Gray Tank drain open. Got foul odors in coach, even with water in traps. AAV's seemed OK. Closed Gray Valve and odor stopped.
No proof, but my working theory is that the open valve allowed odor from the campground sewer system to circulate into the Gray Tank, and some of that flowed out of the Roof Vent, flooding the coach with it from the upper outside.
