So are we worried about mold developing from condensation from interior sources of moisture (breathing, perspiring, cooking), or are we concerned about mold developing on the inside of the metal exterior? If we were to have a foil barrier with the foil facing inwards, would we not be creating conditions where moisture would be kept inside, as though we were baked potatoes in a foil jacket?
If we have a foil barrier glued to the van walls followed by foam or fiberglass insulation and then the interior wall panels, does the foil barrier do anything?
I'm not even sure if we are insulating to keep in warmth during cold weather, or to keep out the heat in the summer... Can anyone enlighten me?
For what it's worth, we live in the maritime Pacific NW and would do most of our camping in western Canada and the western US.
