Wife and I drove into town to buy a burger this evening with a temp of 71. By the time we got home an hour later, it was 46. I even winterized the Trailer this afternoon. It's been two years since I've done that! I probably could have left the heat on, but since they're predicting temps in the low 20's and wind chills well below that, I decided to save the propane and go ahead and play it safe. This way I can go ahead an sanitize it next week before we leave on another trip.
