Interesting you say this, that was my thought also. I’m in the habit even at home of conserving which is why I was surprised. Although I have not been monitoring what the bride does. We talked about it and I think this could be part of the problem. The other piece is that it seems to take some time for the hot water to come up in the shower even this hot summer. Someone on the forum mentioned that when dry camping they use a bucket to capture the cold water until it gets warm and thinking of that also. We usually have sewer hookup and had been avoiding keeping the drain open so the tank would be relatively full when draining the black. As someone pointed out I can keep the dark open and close it for the last couple of days.
