I too used to feel as you do about the DC Refrigerator. Now that we've used it for a couple years (our last trailer had one also), I've come to really like the DC powered refrigerator. The 2 extra cubic feet (8 vs 10 cu-ft) of space inside comes in very handy and it works really well, no matter how hot it gets outside. I only sized our battery plant so we could boondock for a few days so we only have 2 100AH lithium batteries (I could easily add more) and a 400 watt solar panel. We also carry a 4000/3200 watt generator, but haven't needed it so far. So, I agree with Lantley and the others above, that you could buy a lot of lithium batteries for $1000.
The biggest issue we have with boondocking is the Furrion instant water heater. It wastes SO MUCH WATER!
