^^^ we spent a night on galena summit and ran out of propane in a slide in camper. 7.3 would not start the next morning. we flagged down the plow driver to see if he happened to have some starting fluid. he didn't, but informed us that with the nasty winds blowing it was -30 degrees that previous night. freaking frigid... our buddies in a tent were fine, but we froze, lol.
we bought a 0 degree double sleeping bag. a few years ago at my sisters house in wonderful rigby Idaho we were visiting for thanksgiving. after a few drinks I talked my wife into trying out the new bag out in front of their house. I said if its too cold we can just run inside. wife was game to try. it got down to -5. it was fine inside the bag, but lordy was it tough getting out of said bag. I got up at 7am to use the bathroom but wife stayed out there until about 10.
we now have a mr buddy that we use to preheat prior to bed and when we get up. its a lifesaver for my wife with her condition. its completely changed her ability to get out of bed in the mornings.
