In terms of the wiring, it all depends on what you want. If your current one is AC only, wired to your inverter, and you didn’t want to do any rewriting, then you could put any kind of fridge in there you wanted.

If you wanted the fridge to draw straight off the LL batteries and not the inverter, then you would need an AC/DC model. More expensive and a bit harder to find.

Either way, there’s a distinct possibility you’ll have to do a little bit of trim work for a nice, clean, finished look. Take a look at Vitrifrigo. They’re made in Italy and the brand used as OEM by Princess and OE. We put one in our previous boat and it was a REALLY nice fridge! They have both kinds of voltage options.
