Replace 1210 norcold with residential fridge

I know this is an eight month old thread but our Norcold 1210 went toes up today. DW smelled ammonia yesterday (I didn't). I suspect that means the cooling unit has failed.

Is the JC-Refrigeration really a DIY project? I'm not even sure getting it out of the slide past the island is a DIY project. How long does installation take? I'm pretty handy. Is there an installation video online? I found the installation manual.

We have a generator and are past our travelling days - we move it from storage to the RV park only.

We're only here on our winter snowbirding trip for another three weeks so we can muddle by with our bar fridge. Next fall something has to be done.
