When testing my coach outlets with a plug in tester it indicates " open ground" on all circuits when I am powering with my portable generator. The GFI circuits do not break but show the same open gro...

A ship at sea is wired to code. When it is on shore power, does the power cord have a ground conductor? The electrical code will also determine that.
Shorepower is ungrounded three phase 450 Volt, 60 Hz, power to a submarine.
Thanks for the reply and information.
The Lake Freighters and Ocean Vessel’s I’ve hooked up get a 575 volt 600 amp 3/phase power cord with a ground conductor and Electrical Inspected. We do on occasion supply a three phase step down transformer (575 to 440) that is grounded and bonded to the electrical code. We used to use 2400 volt overhead cranes to unload and load; this is why it is so important to understand grounding methods.
But my point is that even connecting a generator to a RV is not a simple play & play event.
