I just threw out my Dometic NDR 1292 that NEVER kept anything cold. On our last trip up to the Kankakee Il., area the fridge temp got up to 50 degrees and spoiled everything. It is now trash.
Have a Whirlpool 11 cuft that has more interior space than the old 1292 and will be able to put a pull out pantry next to it.
My coach has a 2000 watt inverter that normally runs the two TV's the microwave and nothing else that I can locate. I ran a new romex from the microwave area to the fridge cabinet that will allow it to run on Shore power, Generator and now inverter.
I have two large house batteries that will power the fridge when we are not running the genset or on shore power. I have room for two more house batteries that should power it for a day or more if ever needed. We don't dry camp and if we did, I'd install a couple of solar panels to keep the batteries charged.
Goodbye to soft ice cream and soured milk. Good riddance to the Dometic NDR 1292, look for parts on E-Bay if you have one of these. My cooling unit (what a joke) was bad.
