Insulation! After considering a few different options, I ended up going with @3M Thinsulate. It was super easy to unroll, measure, cut and adhere to the walls. I used one 30’x60” roll of SM600L, and another 20’x60” roll of AU4002-5. Love how clean the process was. Also jammed a bunch of it in all the little nooks and cracks of the van. Gotta stay warm this winter! 🤍
