I am looking for information regarding the old type ice boxes found in my pup. I have never used it. It has one bottom shelf where an ice block can be placed. A drain hole is located in that plastic shelf. This ice box has one shelf. Does anyone use one of these???? I am thinking of giving it a try. I hope to place eggs, cheese, corn on the cob, lettuce. The type of things that you don't want sunk in the ice of a cooler. If you use it how long does it take to even get cold? Does it stay cold? Do they leak out the door when the ice melts? We dry camp. No power, no battery, no propane. Right now the ice box is used for storage. Should I keep it as storage?
