Inverter install transfer switch or .....

Do be aware that there is a reason that RVs generally use the absorption refrigerators, not residential units. It is because residential 'fridges (a) do not run on propane and (b)are much more demanding on electric.

A residential 'fridge has a compressor, so that just like your AC, it will draw rather large amounts of power whenever that compressor starts up. You will need a 2,000 watt or larger inverter, and that is going to be quite wasteful of power at all times except for the 2-3 seconds that the compressor is starting. People who are boon docking or otherwise NOT on shore power are not well served by a residential 'fridge for that reason. As others have mentioned, if you go that route, you will have to install a massive battery bank to feed it, and you will have to run a generator a lot every day.

The above colored statements are not really true. You can use a small 600 watt inverter to power the fridge. You will find that most residential refers will consume about the same amount of watts that a absorption refer will. The Samsung that is very popular consumes about 5 watts of power. You do not need a "massive" battery bank to run the refer, most are using a couple of 12 volt batteries or the equivalent in 6 volt systems.

We have a residential refer and are quite comfortable going 8-10 hours without running the generator. The new refers are much better insulated and are capable of going longer without power than the absorption types. We had a problem with the transfer switch and went almost 20 hours without power to the refer and the internal tamp of the refer never got close to 40 degrees and the freezer was still below freezing.
