Craig - Welcome to the family!!!!! If you can find a MONTANA OR MOUNTAINEER brochure I think in the back few pages it will discrip the package. More insulation, double pain windows and a few other things... Makes you want to go the Alaska and try it out. Oh wait It gets cold enough here in KANSAS to try it out ha ha.
