I guess I keep a small heater in my rig just to ease my mind some. I would prefer the interior not get really cold. I keep the cabinet doors and bathroom door open, but I don't think it does much good, just peace of mind. I also don't worry much about the big tanks getting heat. I make sure the lines have antifreeze so they won't freeze. A plumber once told me not to worry about the p traps, that if they do freeze they will not break. I put some pick stuff in them anyway. I don't have the washer problem, but I think I would somehow check those lines to see it they get water in them, just in case.
