I will give you one example of why that would have been a bad idea in my case.

This Spring I was doing my routine cleaning including washing down the bathroom shower. Evidently a tiny amount of water went into my converter. When I noticed the clock on my microwave was dark I checked the GFI outlet that feeds my shore power. It was tripped. ... long story short ... turning on the converter breaker tripped the GFI. When I pulled the converter board I found a few drops of water between the circuit board and the metal case of the converter. Some current from the switching mode converter circuit board was leaking to frame ground. A dangerous situation.

As part of a previous post, I said that a GFCI protects people not equipment. I still stand by that statement. Think about this, in my (and probably your) RV, only the circuits where I can come in contact with water and an electrical circuit have this protection: kitchen, bath, and outside receptacles. My converter is not protected, neither is my TV, refeer, or hotwater heater. Even though the GFCI tripped because of a few drops of water inside the converter box, there was in little danger until the component was openned when engerized. The tripping did help to very quickly determine that the convertor was compromised. You will read in this and other forums of the common items causing GFCIs to trip are hotwater and refeer heater leakage currents. Again most people are not in danger when these items fail. The protection in the RV is not compromised by using a dedicated non-GFCI receptacle in the garage since it is no different that a CG pedestal 30/50A receptacle. The 15/20A GFCI in the pedestal is there for protection when using an electrical device outside an RV, bypassing the RV GFCI protection. JM2¢...
