We spend the month of December, and into January, in Georgia each year. Admittedly, the weather is not extreme, but there are many nights in the 20's, and Christmas this year had a high of 39 degrees. Many of you more experienced winter campers will find that amusing. We use the propane heater in the morning to warm up the RV, but mostly use a Duraflame heater during the day, and at night at a lower setting. The Duraflame heater is in an attractive cabinet that makes a nice end table. If necessary, during the day, we use a small ceramic heater on a separate circuit for an additional heat source.
