I had no idea this was going to be such a lively topic!! Anyway, I appreciate all the feedback. You guys just saved me some $$$. Well, Cabelas Bucks anyway!!! I filled my Coleman Extreme for a camping trip last Monday and decided to see just how long the ice will last. Today is day 7 and it still has grapefruit chunk of ice. It is sitting outside behind the house, morning sun and afternoon shade. Temps just shy of 100. I think I all ready have a great cooler. As I said earlier this one is 20 years old. Wonder if the new ones are as good or got cheapened up?
