Our group decided this past weekend that we were going to boondock more next year to avoid all of the shenanigans of the party animals at regular camp sites. Our camper gets pretty hot, as I am sure most others do. We do have AC, but I am trying to avoid running the generator so we can enjoy the peace and quiet. I added blackout curtains, mirror tint and a windshield reflector, which all seem to help. What else can I do to minimize heat absorption? We have fiberglass siding, an aluminum roof, and I also added Camco vent covers so I can keep the vents open when it rains.
