I'm not into sewer venting in an RV. And I'm somewhat knowledgeable about residential venting. Basically I know enough to be dangerous. The mouse house gray water tank has two drain lines going into the top of the tank. Both drain lines have have 1.5 inch vents teed into those lines. The black water tank had an 1.5 inch vent line that tied into the gray water tank vent. I understand why a large vent is needed for a standard residential toilet. But an RV toilet flushes in a much different manner. And with much less water volume. So I need to figure out just how small a vent line I can get away with for the black water tank. And I mean seriously small vent. The rear drive in shower is 42 by 57 inches. The shower, bath, and kitchen sink will all go into the gray water tank. And I know that some gray water should go into the black water tank. But that's just not possible. That issue I can work around.Bob Dunahugh78 Royale.
