Well, if Rick 4x4x4 replied to this well written article, then I must also.
Mike, this is a fine piece re: cold weather camping. After retrofitting our ancient ill-insulated, one-season, wood framed Lance with insulation into and on every place possible, I still learned a lot from your piece about traveling and living in cold storage. I never thought about the stove top vent insulation or a thick insulating pad under our carpeting. I used 2 inch thick, foil covered, both sides, R-11, closed cell foam blocks cut to size and glued to inner walls and right over the pass through window, and all 3 front windows with some fiberglass batts and Reflectix in non flat locales like around plumbing and stuffed into drafty openings. I glued these cut blocks on 2 sides of the fridge box, a notoriously air leaky environment. I left one low opening door to the truck bed uninsulated and openable to let in cyclonic fresh air in for exhausting the moisture up through the roof vents.
