We have used an Emerson ice maker in the past. Takes a while to get going and produces "soft" roundish cubes with a hole in the middle. We had to be home when maker was running since ice would melt if left in maker. We filled gallon freezer bags and put them in the freezer in fridge. Eventually it froze in a block. We winter, semi full time, and have decided that it is easier to pick up ten pound bags at camp store and put in freezer. Less hassle. If we had to worry about cost of buying the ice, we would give up rv'ing.
