If I were full-timing a residential refrigerator would probably be the way to go. For my purposes now, RV refrigerators and portable ice makers are the most convenient. I've tried my portable ice maker in the kitchen and in the basement. We tend to like it in the basement. Less convenient, but also less noise which trumps the less convenient thing. Plus, the portable ice maker makes this soft, airy, really good ice. As far as water through the door, I guess I would prefer both. The water gets chilled, which would be convenient at times.
