Recently purchased this Class C. I noted on our first trip it had two release handles for black tanks, and one grey. Anyone know why?

That's pretty strange. Are you sure it's not a release handle for a galley grey tank?

We have two valves on our 28QB Freelander black tank and one on the gray. Our toilet is located on the passenger side of our unit. I have read on the forums that the RVIA code requires a valve within 18" (I think) of each tank. I speculate that the second valve on our black cross drain is there to prevent gray water from flowing into the cross drain when dumping the gray tank.
I keep all valves closed to keep the cross drain empty in the event road debris were to break the cross drain.
Also, when dumping I fully open the black valve nearest the dump first (after connecting stinky slinky) and the black valve nearest the black tank second. You want the head pressure from the tank to help clear the drain line. I also close the tank black valve and refill tank and flush tank a second & third time if on full hookup or no line at dump station. Finally I close black tank valve, driver side black valve and then dump the gray tank to help clear the stinky slinky.

One handle for grey, one for black, one for washer/dryer

No washer/dryer. Like HOWie said, one valve at the black tank, one at the Y where black and gray come together.
