Residential fridge and dry camping

I have read these threads with interest for the last 15 years thinking someday my Norcold was going to fail and I would have to replace it with a residential or another propane electric. I dry camp 95% of the time and tried to compare costs going to residential. What I have gleaned from these discussions is that I would have to add 2 more batteries, at least another 100 amp battery charger maybe more if I wanted to reduce generator time, a pure sine wave inverter to run the residential, some solar and all the cabling to keep the 4 6 v GC batteries healthy not sure If I missed anything. My question is what would all this cost vs a new Norcold if one had to pay someone to do all this work?

On our 98 gasser, I installed an extra outlet from the after market MSW 1KW inverter, I had installed previously. With two 6 volt batteries, it supplied the RV fridge while underway, but not for long, when standing alone. Most sure a residential would have done a lot better. Either way, one doesn't need a huge fancy fridge, that requires a PSW inverter and adding a couple of extra batteries would be optional. I think given all the options and especially on an older coach, I'd go for a $400 residential and with keeping the batteries charged with the genset, as required, when boon docking. Probably could use some extra shelves built on the side for taking up the extra space, after making the switch, too.
