What does the concept "ground fault" mean when your power source is not grounded?
A RV is grounded as an appliance when plugged in to shore power, via the ground wire in your power cord, which is supposed to be connected to the ground used by the power company.
Connected to a generator, is there a ground reference for the generator, if you don't drive a ground stake? Does a ground fault matter when the generator is not grounded?
Thinking about it this way, leads to no GFCI necessary, maybe?
As I understand it, the GFCI monitors current flow through the Hot and Neutral posts and shuts off flow if it see's more current flowing from Hot. When that happens it determines the flow of current isn't taking the correct path and must be going someplace else - like us!
Because of this it isn't necessary to have a ground with a GFCI.
