Can I steal this subject??? I get the black tank odor only when my class C is being driven and the toilet is flushed. NEVER happens when used while stopped. Is blockage in vent pipe a likely cause??
Since venting appears to works properly when parked I would say the vent is open but suspect the problem is air pressure in the tank or a negative pressure in the coach when moving. You can somewhat simulate a negative coach pressure (or positive tank pressure) next time your parked by closing all the windows and doors and turning on all the roofs fans to high exhaust. The fans are going to pull air from somewhere and when flushing you'll have an unrestricted direct line from the roof vent into the tank and up into the coach.
