Thanks John, we usually keep a pretty stout heater in that area, so that helps keep the cold back. I do have more plastic to install on the windows if needed, but I have to remove the window treatments to get to the blinds to get to the windows. Just being lazy on that one lol. Honestly we usually keep the trailer cooler than others would, we sleep better, but there are times when I kick the heat up for the wife during the day or the visiting kids or grandkids. I reassessed everything last night, comfort vs how much propane we have used and I'm pretty pleased. I heard my wife bragging last night to the Dil about what all we have done to the trailer, made me feel pretty good lol.
