Weekend Warrior and insulation are not words you use together unless you are the one adding it. We don't go to extremes to block out windows and vents because we needed the ventilation to keep down moisture and we like to be able to see out the windows rather than be in a dark box. I know there are people that are very frugal with resources and go much longer on the same, but we bought the RV for comfort and use it more like a second home rather than a lesson in conservationism. We camp with animals so even if we are away for most of the day, the RV is still heated or cooled for them when they stay behind. We're out about twice a month year round with many 3-night trips allowing for getaways while still working 40+ hours and commuting an additional 10 hrs each week.
