I also have two Coleman extremes, one is perfect for a deer and two for elk obviously. I freeze 12 milk jugs full of water and bring them all in one ice chest to start. Great way to bring home meat, doesn't have the meat sitting in water nor cost a $ 100 for ice lol. If I'm staying a week or longer I rotate the milk jugs overnight in the camper freezer. It's been a good system for me. Good luck everyone this year.
