I never boondock and get by just fine with four house batteries and a MSW inverter. I installed a Samsung RF197 residential fridge, which the manufacturer has published will operate on a MSW inverter. The only issue I see is the RF197 is no longer in production, so I do not know what is currently available that will fit in a similar opening and operate on a MSW.
One addition point, many people have stated the reason the RF197 operates on a MSW is because the compressor is a DC motor. This is not true. The two internal fans are DC, but the compressor is most definitely an AC motor on my fridge. The only difference I've noticed is that it's not as efficient when operation on the MSW inverter and actually draws slightly more current vs. clean AC power (generator or shore power). Good luck and the change is well worth it.
