my biggest regret was in the how to keep perishables good. I tried it all. of course I started with an ice chest because that's the way it's always been done. well that only works for a few days or if you are close to snow. as I started going further out into the backcountry for longer periods of time, ice wasn't cutting it. then I tried a few of those 12v coolers, don't even waste your money. then I tried a dorm refer, power hog and not built for rough use didn't last a summer. then I tried an RV refer, well it worked good but now I needed to carry more propane and instead of making ice runs I was making propane runs. I also tried dry ice, it's too cold, and would only last about a week. so I finally bought a 12v refer, dang why didn't I just do that to begin with. would have saved a boat load of money. I now have two 12v refers and will add a third to use as a freezer. highdesertranger
