Big thing for me is the quick cool down, much more consistent temperature control and no hazardous chemicals inside (compressor fridges use enviromentally safe R134.
Hardly environmentally friendly -
see here. It has over 1000 times the "global warming potential" of CO2. Better than the old R-12, though.
Ammonia and hydrogen, on the other hand, have very little environmental impact. Concentrated ammonia can be corrosive and toxic, but that's about it unless you dump it on ground/water. A slow leak from an RV fridge isn't a threat. The vast majority of ammonia is made for use as fertilizer.

A typical Secop/Danfoss compressor pulls less than 5 amps at 100% duty cycle and most time is pulling less than 2 amps. An ammonia fridge with auxillary cooling fans is approaching that and it's basically all the time.
Huh? My Dometic RM2652 draws about 0.7 A when running on propane, and I haven't bothered to disconnect the anti-condensation heater between the fridge and freezer. <1 A with the interior fans on. And that's when it's drawing power to keep the gas valve open.
