running DP's durining quiet hours

We have a DP and what I try to do regardless of when we are leaving is quietly stow everything and idle the coach just enough to air up the brakes and air bags. Then I move to another location to hook up the toad if possible. That way I'm not sitting idling while hooking up the toad right next to my neighbors. There isn't much else I can do. My wife and I both work so sometimes it is unavoidable. We also sometimes try to leave a day earlier and dry camp at a rest stop on the way home to be able to leave later in the day.
