I have a 2013 Crossroads Lincoln 39FN. I drain and fully flush the blank tank put in additive with a couple of gallons of water. I am getting a terrible stink after a day or so when I run the bathroom fan. So I drain the black tank and every time the colored water is bright and sparkling no sign of waste until ten seconds or so then the waste and paper will start to empty. It is almost like the additive is in the lower part of the tank not mixing with the waste in the rest of the tank. Any suggestions.
One thing that can affect the smell from the toilet is the location of the roof vent for the black tank with respect to the bathroom exhaust fan. If the tank vent is too close, when the exhaust fan is running and the toilet is flushing then the exhaust fan can draw air in from the black tank vent - through the black tank - up through the toilet - and into the bathroom. Above the small window on my Class C is a Cyclone Vent. It can help - some, by having the wind point it and draw air from the blank tank - away from your RV.
