I made the switch from RV to residential refrigerator. I note that you are buying new, but total long term cost was something I thought about quite a bit.
I can supply my own electricity with solar but I can not supply my own propane.
The RV refer would have cost 4500 vs the 1500 I paid for the residential. That $3K can offset the cost of the needed electrical upgrades.
Unlike other posters above, when I have added the planned extra solar up top, I don't think that boondocking will be any problem at all. I expect that my issue will be filling the gray tank.
I also find that while traveling, finding propane that is easy to access is a PITA. Since I no longer have any risk to my food if I run the propane dry, I no longer have to worry about monitoring it as closely as before.
Mentally I also feel a bit of a relief that I don't have a burning flame inside my RV.
I don't really see any down side, just differences. With inverter and solar technology today I see no good reason to do it the old way.
