Did someone install 120V refrigerator with the same idea?
I did it in vintage Airstream trailer that I was restoring and having inverter, I did buy $120 bar-sized refrigerator for it.
I used it for 1 season before selling and with hookups at campground -used the 12V source only when driving.
It did work and I estimated that even in CA heat, the single battery should power refrigerator for at least 3hr, what was good enough for any stop we might have.
Good inverter makes minimal power loss and purchase price sure makes big difference.
