I think you are right on.
I do have to say though, that except for my black tank monitor, my monitors have always worked just fine.
I can get the black tank down to empty, if I use the built in flusher, and then it works showing increasing contents. Then empty and time to flush again.
I thought I saw somewhere external sensor systems. If they work, seems we would have much less problems with them.
