This weekend was our third trip in the popup but the first with below freezing temps. Got down to 27 degrees both nights, 50's during the day. We used 2 space heaters to stay warm in the camper at night and put reflectix in the windows of the bunk end that we used. The reflectix also helped to keep the light out from street light that was just outside our camper. Who puts a street light in a campground? We didn't use the water system except for the sink drain. Set an aquatainer beside the sink for water supply to clean dishes. We had company this time. Some friends of ours were there in a popup as well. We had a really good time. Next trip is Fort Pickens In Florida in a few weeks.
