I watched that video. It is surely interesting.
Since we boondock most of the time, the typical PC-installed 2-way propane/120V fridge is right for us. But if traveling from one RV park to another, especially during hot summer 90+ conditions, I see the attraction of a 12V compressor type.
One thing I scratch my head about are the restrictions on propane usage. Our 3 to 4 week trips out west, we run the fridge on propane nearly 100% of the time, including while driving. The only time we make any kind of change, is turning off the fridge while filling the main 55 gallon gas tank. On rare occasion, we find ourselves in an RV park for a number of days. Then we switch to 120V. Otherwise it's always running on propane.
Our first major trip in our PC back in 2007, we were green horns regarding a fully self contained motorhome. We were oblivious to the amount of propane that was being used. One night we ran the furnace, but otherwise just cooked, made hot water for taking showers, and fridge usage. The 3 week long trip, we ran out of propane during our last day communting back home, roughly 8 hours away. Ever since, I make it a point to fill once during a 3 to 4 week trip, and again at the end to have a full tank once back home.
