Have a 2013 320rs, it has 3 vents in the roof. Two are near the centerline and one forward and to the left side. Witch one is for the black tank? [They all smell the same.]
Also any ideas on checking for AC vent blockage, bedroom AC doesn't seem to blow much volume, cold but not much flow.
Several units have had Styrofoam insulation in the blocking the AC vents or other obstructions under the filter element. You might check these. If you open the vent on the unit itself and have good air flow, then you may have an obstruction in the ducts or at the vent. I had to check all of my AC vents and almost all had some of the Styrofoam material blocking air flow. I carefully removed the covers to remove the obstruction.
320's have 2 gray tanks and a black. are you saying the gray tanks have a common vent? I want to put a wind vent on the black tank to help draw out the odors.
It would appear so. If you pull off the cap in the basement storage and get a flashlight, you can see all the way to the roof cap. Nothing else joins that pipe.
a towel around a vacuum hose and stick it in the toilet valve ( water off LOL) and then see which vent is blowing air.
Clever!
