I'm a big fan of 12V compressor fridges. They're reliable and perform well, something that seems to be hit-or-miss with propane absorption. They do require a decent battery/solar/charging system, but this benefits off-grid camping generally - not just the fridge. Install 150W to 200W solar (1 - 2 medium panels), and this is the key: a 12VDC input charge controller for the batteries. This, combined with heavy-gauge wire from the tow vehicle plug will allow you to properly charge your battery from the TV in an emergency (no solar). And charge it *effectively* and fast thanks to the voltage boost from the charger. You're no longer at the mercy of voltage drop over long wires. I have such an electric setup (sans the expensive compressor fridge, some day) and can charge my battery at 40A from the tow vehicle. It doesn't have to idle very long to top off my batteries.
