I really think propane fridges are on their way out. The reason why I say that is solar has become so very cheap. My 200 watts of solar with controller only cost 325.00 with me installing it. That makes them completely viable even possibly better than propane. The 12 volt fridges are just superior in every way to the propane fridges. I have had a half dozen propane fridges. They all did fine under 90 degrees and they all had to be used very carefully above 90 degrees. Its humorous how many times I have told my wife and kids and now the grand kids SHUT THE DOOR YOUR LETTING THE COLD AIR OUT. You also get more space for food storage in the same foot print.
All that being said I still waited for my porpane fridge to die before ordering my Nova Kool. Now I haven't received it yet but once I get it installed I will be the first to give a honest opinion once I have it in use. But I just can't see not loving it to the max. Never ever ever LEVEL again for the sake of the fridge. That's big in any camper and huge in a Truck camper.
