Some of you might remember a question I posed, a while back, concerning how to keep water in my Jeep Wrangler, outside over the winter, with freezing weather conditions. Being a soft top, the interior of the vehicle is virtually uninsulated, so if it's freezing outside, anything inside the Jeep will freeze too.....including bottled water! After much consideration, I've decided I'm going to try out a couple of these Coleman 1-gallon jugs, to see if they're as good insulating room temperature water inside from freezing, as they are insulating iced beverages inside, from melting. I figure if I fill one halfway with water, and put it in my chest freezer for a few days, I'll get an answer, one way or the other....and, hopefully, NOT a mess! https://www.walmart.com/ip/Coleman-1-Gallon-Jug-Red/13848699?u1 There's other colors available, but for whatever reason, Walmart has these for sale at 1/3 the cost of any other color.
