I've added IR-blocking tint to the front side windows and windshield (imperceptible visual tint on windshield) and it has made a huge difference in comfort. Next, I've started thinking about adding insulation in all the body panels like my old conversion van has. RansomRidge has a great writeup on how to access under the headliner for this. Since I have a passenger version, I have many more panels to remove and it's going to be a tedious job keeping things from breaking. Are there any resources on how to disassemble the interior the right way?
