Uh, slightly different way that GFCI works: it is based on the current in the safety ground wire, not a "voltage imbalance between hot and neutral" (that is the line voltage or a nominal 120 VAC). The GFCI trip point is nominally 6 mA (or 0.006 Amps). If it is tripping, there may be a problem with how the grounds and neutrals are connected in the RV. A bigger issue is if the ground and neutral are connected together somewhere in the RV. They should not be connected together anywhere in the RV. If you have an Ohmmeter, with the power cord disconnected, the inverter off, and the generator off, use the highest resistance setting and check the resistance between the safety ground and the neutral connection at the end of the cord. There should not be any indication on the Ohmmeter. If there is, then there is a wiring fault in the RV.

Just an update for power usage. We took a trip to Pigeon Forge. The 750 Watt inverter worked perfectly to power the fridge. Held a constant 35į for the whole trip. It's amazing, we have hard ice cream for the first time ever. This is the best modification we've ever done. Thanks everyone for their help!

I the fridge directly to the outlet which tripped. I ran it to an outlet at an adjacent site which also tripped. I found another motorhome owner with a residential fridge and he had the same problem so it is the facility. When we return home we will look for a different storage facility. We packed the fridge before starting our trip and it cooled down to normal within an hour. Icemaker did not work until we figured out that the icemaker is in the off position when the glass with icecubes icon is on. I had to run the test button on the bottom to get it to start our first tray of ice.

I have helped so many Samsung fridge owners with their ice-makers that I've lost count because I was faced with the same dilemma.

If you take a magnifying glass and look at the ice cube Icon you will see that it says NO ICE. Therefore with the Icon ON the ice-maker is OFF. With the Icon OFF the ice-maker is ON.

Yep. On is OFF and OFF is ON.

BTW, I installed a Magnum ME-BMK last weekend. I turned off shore power and ran the fridge on the inverter to see how long it would go. The Samsung only showed to be using 10 amps DC. Ambient temperature was around 60, so I assume the compressor was near it's lowest. I ran the Samsung and the Dometic outdoor freezer for 30 hours and the batteries still had 66% SOC. I know this will change once we experience hot weather, but I am pleased with all, the battery upgrade, the battery monitor, and the performance of the RF18.
