My gray tank is full when the shower no longer drains.
My black tank is full when the toilet burps when I flush.
My gray fills up long before the black. I put a valve on the main drain pipe where you connect the drain hose. With that valve closed I open the gray valve, wait a few second, then open the black valve to move some gray water to the black tank. Then close both valves. That gets me at least another shower before to the dump we go.
Do you have a picture of that setup?
Both of mine go to one main drain with drain valves for both tanks.
You can do this trick by just leaving the cap on the end but you will have to deal with the “extras” when you pull the cap to connect the hose at the dump.
