That's what the UJOR roof rack will be for. Hopefully I can get a full length one from Chris. Package length limits are messing me up.
I'm just using 3/8 foam board with the foil facing out and vynel tape. It's been in the 50s the last two days and I've been overheating in the van while I work.
Not sure what I will do for the bottom half. Part of me wants to cut out the inner walls and do more foam board. Fiberglass bat insulation would trap a lot of moisture. Not something I worried about in the aluminum ambulance, but a problem with the steel van.
My phone isn't playing along with photos, but the headliner came out along with the roof mounted spotter light, and three more antenna mounts. I was racing the rain so I patched with flashing tape. I'm guessing my best bet for a permanent fix would be body filler.
I completely removed the ford wiring harness that runs along the ceiling corner and ran it inside the wall cavity. It requires unhooking the taillights and some bloody knuckles. While I was in there i also ran one power feed halfway down the side of the van, and another 2 all the way to the rear corner. Perhaps I should leave it open until I make a decision about a backup camera?
Pro tip- if you are stuck in the rain, or otherwise cant pull the third brake light off disassemble the rear door light completely and plug the wiring into the wiring harness as you pass through the rear roof corner. The connector for those lights won't reach all the way.
