I have a 4.3 cu ft NovaKool refrigerator in my Tiger and run it off two 6V batteries per 200W solar. It even has a small freezer. It is very efficient, is less vulnerable to ambient temperature changes and, as has been observed, doesn't require leveling. Admittedly, this was the one item in the Tiger I had been most concerned about, having always had propane refrigerators in my RVs. But the concerns were needless and I would never go back. If I needed a bigger refrigerator, that might require more solar.
