As the thread starts. I need your opinions. I just realized I forgot to winterize my cassette toilet. And apparently it's going down to the upper teens tonight, but above freezing during the day. My camper is in off site storage 45 min away and I can't get off work until 7 pm. The storage lot will be closed by the time I get there. Do you think it will be OK. I'm going to try and take an hour off tomorrow so I can get it done, but no can do tonight.
