Refrigerator on while towing?

The thing to always keep in mind is that the refrigerator has to be kept within 3 and 6 degrees of level if your stopped. We had our refrigerator go out within the first year of ownership, thankfully it was still under warranty. I think it was while traveling we'd stop and the trailer would be sitting out at maybe 10 degrees or so out of level. I didn't realize that they were so fragile. And they take so long to cool down once they warmed. In this day and age you'd think they'd come up with an RV frig that would cool down fast, with in an hour or two, and be able to run at all normal angles of lean found in parking spaces.
