I equivacated for 3 years. A friend had installed Engels and loved them. Other cruisers had the Engel chilly bins and loved them. We purchased a 30 liter portable to keep refrigerated stuff while this project was happening. It worked great. We had high hopes. The three Engels are in and working great. The space is equivalant to what I had before but first and formost they are much, much quieter. Second we can shut down any one to defrost and use they others to keep the food cool and third; when cruising if we get low enough on refrigerated supplies we can shut one unit down completely and save more energy. All in all it is 2 thumbs up!
