You are correct -- 3 holding tanks -- black(toilet), grey (shower and bathroom sink) and grey (kitchen sink). All three with separate pull handles but only one discharge point = one sewer hose.
Some people open both grey pull handles if camping with no hookup for sewer to increase total grey water capacity -- especially for the shower. This is controversial -- all do not agree that they want to mix the more greasy water from the kitchen with the bathroom grey tank. I have only done it once several years ago when in a county park with only a dump station. if you do it you need to have one of the Valterra shut off valves installed at your tailer discharge point.
Those valves are great even if you don't do the above since there is alway some liquid in the pipes that moves in transit and accumulates at the discharge cap.
