Here's item number 2. The cabinet under the pantry (washer/dryer cab?). We noticed odors coming from the area between the fridge and the water closet. We just tracked it down to the top shelf of the lower pantry cabinet. It has the same smell as the black tank. I noticed an opening at the rear right top inside corner that seems to go into the wall. Not only do I wonder why there would be any opening there, I wonder why the blank tank smell would be in the wall. There is a vent for the tank, and it has one of the turn in the wind and create a negative pressure at the vent hole things on it. Looking underneath, in the basement, there doesn't appear to be any leak, but as others have noticed, it's not like there is an access panel there.
Do I need to pull the commode?
