Rv Refrigerators vs Household Refrigerator in your Rv

Really long winded run on paragraphs for:

Residential fridges if you have good source of AC power or good source of charging battery and using an inverter
Absorption fridge..level to operate

So which absorption fridge did you recommend to the engineer?

And you don't need to be an electrical engineer to set-up solar panels, battery bank, inverter and run of the grid.
