Here's a list of the items I bought and found to be best and best prices for what I was using:

For the fan, get a tube of the special caulk and the sealing kit (links below):

This is the insulation kits I used, think I only bought 2 kits but you might need 3 or more if your van is bigger:

and I used the Reflectix on the roof with spray adhesive as the first layer then the insulation over it and taped it all with tyvek tape, didn't bother using it on the walls since didn't see it being an issue after using a heat gun all summer to test out the wall and roof temps:
