Thanks for the replies. I should have been more clear in my original post. I plan to winterize the unit after our trip in two weeks. We are experiencing an "artic blast" for two days here in TN. We typically do not experience this type weather until January/February. I have already winterized my horse trailer LQ for the year. Ultimately I would only be looking at the temps for two nights. After that they are calling for the temps to jump back up to the 60s. I was just questioning if the all the extra heaters and insulation would keep me protected those two nights.
