Hi Ross, i live in south florida where it doesn't get to cold. it's actually 70 degrees right now and feels like 80 when i stand in the sun. But my question is if you left a deep freezer or cooler outside wouldn't that act as a freezer even not being plugged into power? or couldn't you just put stuff into ziploc bags and bury it in the snow? sorry if the question seems dumb but i know i can leave a pan out in the sun here and it will get hot enough to cook eggs. so using the weather to our advantage can help save on our electric bill
