We have the refrigerator as a second unit for about 4 years in the caravan and motorhome now in use. Although it is operated while driving through a voltage converter (2000W, including gabs problems) he still runs. We are satisfied with the cooling capacity. But you should note that (at least in our model), the cooling is carried out via the side panels! Dehalb following note. Quote from the manual: distances comply with at least 5 cm from the ceiling and 5 cm from the walls.
