So far I run my 120V air compressor on Ford inverter, so that is good.
It is small compressor, but you know they need high amp for start, what makes them good supply testers.
When it comes to "dirty" voltage - fridge uses resistor heating element and they will run no matter how all the power surges.
Additional, I have lot of stuff in my garage, so instead of buying 120V relay, I will use small 12V power supply and 12V relay who I already have.
Used them this way in my house for humidifier, what with addition of WI-FI plug made for home automation. Those small power supplies will run on anything between 70 and 250V.
I don't plan to use my camper for next 2 months, but when temperatures drop a bit from 115F we have daily, I will get on the project preparation.
Main issue will be finding safe way of running 120V cable from cabin to fridge compartment.
Ford installed inverter behind rear seat, but the plug is on dashboard. I already check that it would be hard to tap into inverner harness, so running the cable to front plug will be probably best option.
