Thanks Doug, that will be my first avenue of troubleshooting this afternoon. If the source of the trip is the heating element, and it goes away when they are unplugged, any idea why the fridge would operate normally on the genset? The ice maker is not plugged in, it has a separate 120 plug that I have not even attempted to plug in.
A ground fault does not mean the heating element doesn't get hot, merely that some voltage is leaking to ground. If it's a high-resistance fault or one at the neutral end of the element, it would behave essentially as usual (but, of course, be more or less of an electrical hazard).
If the generator has a neutral/ground bond, as a built-in RV generator ought to have, the GFCI should trip under generator power. (Obviously, that's just the GFCI in the motorhome, not the one in the house!)
