Something that I do not think I mentioned but when I check the system monitor panel it shows that the holding tank is 2/3 full and I have never gotten it to empty completely and the gray shows that it is empty. I have also read that in some cases the shower or bathroom sink could also go into the black holding tank. Have you heard this before?

Showers don't.
Before you start shoving stuff up your sewage lines answer this.
1. Have you physically 'pulled each valve blade separately' for both the 'black' tank and 'gray' tank ?
I.E. > Open one valve, close it, and then open the other valve.
Are you saying nothing comes out of either?
