Great to see your solutions to insulation. Several of us have tried our own idea to insulation solution. It's raised many questions and lead to lots of discussion. We have decided to get together in 30+/- years. We will then take our trailers apart and compare the results. Some of us will be 95 years old or so. Should be an interesting event. You are invited. By the way spending many hours under, on top of, or in an Airstream has no affect on ones mind.
