We just purchased our pioneer rd210 and it has 2 sewage connections The back one is labeled gray 1, sewer connect, and waste water holding. I'm assuming that's black gray tank combo and the one up front is not labeled. Must be gray tank 2. There is only 1 lever on both to release tank
Most have double Lever for the gray and 1 for black.
Confussed
