on our ACE 29.3 we had a slightly different experience on the one occasion that I slightly overfilled the gray tank. I realize that the shower is the lowest drain, but that one was not backing up. It was the kitchen sink that refused to drain. After wondering for a minute why the sink was not draining, when I am so careful of what I put down the sink and should not have clogs, it dawned on me that the gray was probably full. Hubby looked in the shower just to make sure it was not overflowing, and it was not even showing signs of back up. He ran a little shower water, and it did not drain, but no back up, thankfully. I went out and pulled the gray tank valve, as we were hooked up at the time, and all everything drained well. I guess we were just lucky that the shower didn't back up. Anyway, apparently the kitchen sink can be the first indicator, not the shower....
