The GFI/GFCI in the RV is not going to interrupt ALL AC 110v usage... It will certainly affect the bathroom, kitchen, and exterior outlets - but others including microwave, TV's, bedroom outlets, air conditioning are normally NOT on the GFCI circuit...

Most of our rigs have a SINGLE GFCI outlet in the bathroom - that protects only the outlets ON THAT CIRCUIT that are 'electrically downstream' from the GFCI... Nothing on any other circuit breaker is protected... (Some larger coaches may have more than one - but still a limited number covered...)

Now - a GFCI in the HOUSE that is powering the RV certainly would interrupt all AC 110v usage in the RV...

As Ed suggested - try to plug into another circuit - non GFCI - in the house at least for a test... If that works - I would verify the HOUSE wiring for the GFCI and/or replace the HOUSE GFCI... (or provide a separate non-GFCI outlet for the RV... It doesn't need to be GFCI protected - as it has its own for the necessary (wet location) outlets.)

Had a GFCI in my new home (sticks/bricks) that worked most of the time - but when I plugged in one large (attic style) fan would trip immediately... The fan had no issue in a non-GFCI... Opened up the wiring and found an open ground going to the GFCI - fixed that and all was well with the fan. It isn't just RV's that have their issues...
