I don't have an issue running my inverter genny to take up the slack. I'm 'green' but not that green...lol
I still think (maybe I'm all wet) that the more insulation you have between the cabinet the fridge is housed in and the fridge itself, the more efficient it is. I know the first year I had my TC, I was really dismayed with the Amish fridge's inability to keep food even cool so I was about to add 2 fans in the upper cavity (mine intakes and exhausts out the side, not through the roof and when I pulled the outside vent covers off to add two computer fans and saw what the builder didn't do, I was not happy. NO insulation between the fridge cabinet and the enclosure at all and they forgot to add the Dometic required curved baffle at the top though they did install a cheap sleeve bearing fan that was doing nothing but circulating warm are from the boiler and HX throughout the space where the insulation should have been, but wasn't.
I trundled down to Lowes and bought a roll of unfaced pink stuff and a sheet of light gauge galvanized metal and headed home. Stuffed almost the entire roll of unfaced pink stuff between the outer cabinet and the fridge (wearing gloves and a face mask of course, the stuff is itchy). Once I stuffed the void, I went in my shop and sheared the galv sheet to size and roll formed it to the curve I needed to make a baffle for the top of the cooling unit to direct the air flow. The, I added 2 air bearing computer fans (250 cfm each) to the upper vent and used the already in place thermostatic switch to power them. Made a huge difference in the operation of the fridge, it actually refrigerated, what a concept. My issue (and why I'm going to a compressor fridge is) we mostly primitive camp, usually off road and it's extremely hard to get the fridge level enough to operate correctly. Not an issue with a compressor fridge and even though my Amish fridge actually works now, it still takes quite a while to cool down from ambient whereas a compressor fridge will cool down in a couple hours not a day or longer (depending on how hot it is outside).
We already own a Dometic Cool Box and it sits on the floor in the truck cab when we go camping and in my wife's car when she goes grocery shopping. She uses it to bring home frozen food without becoming unfrozen in the summer, we live 30 minutes from the grocery store. She don't even turn it on until she goes to go in the store and when she comes out and puts the frozen food inside, it stays frozen coming home and when we go camping, stuff we need to stay frozen go in it, like ice cream and you don't have to worry if it's frozen or turned to mush in an Amish fridge with it's temperature swings. I'm 100% sold on the Cool Box and I know it will be a winner in the TC as well. Not familiar with the other brands but I'm sure they are just as good so long as they employ the Waeco / Danfoss duty cycle compressor.
