Installing insulation on Tune M1 popup camper

This is some removable insulation I made for my Tune M1 camper. It uses 5mm closed cell double foil sided duct insulation from US Energy, which they advertise as R8, dubious as that sounds. However, the double foil installed with an airgap (velcro in place) results in great heat rejection during hot AZ summers.
The end pieces allow camper to fold down easily and I will leave permanently installed. The side pieces I demonstrate installing here for my first time. I will remove them to close camper to ease the material folding and closing. Then I have some narrow pieces to go over the aluminum rails where a lot of heat bridging and condensation happen without an insulation layer. After doing it a few times now, I guess it will take 6 to 9 minutes total to set up full insulation when needed.
