Most of the small generators (all?) do not bond the green ground wire to the white neutral wire. So much easier for the GFI to trip. A solution to that is to get a repair plug and hook the ground terminal to the neutral terminal. Then plug it into one of the unused 120 Volt sockets on the generator. This makes the system more like what you have in your house. I think but not sure the ONAN generators do bond the two terminals.
Yes I have done this for my Honda 2000 generators in the past but no longer use them since the coach has a 10KW generator in place.
