My previous RV had a built-in ONAN with a bonded NEUTRAL/GROUND. My current RV is a trailer without a generator. If DW decides I need a generator, I will get a Honda EU2000i and an EasyStart soft starter. Since I have a Progressive Industries EMS-HW30C, I will also make a bonding plug.

The OP's Champ inverter genset doesn't have an "open ground" but rather a floating neutral that his PI EMS interprets as an open ground. Simply adding a G-N bond is safe and will solve this issue.
Floating NEUTRAL is the correct term, but OPEN GROUND is what the EMS reports, so that is a commonly used term.

Or just use the bypass. If generator voltage is an issue it will shut down from overload before any issues to the RV happen.
Just using the bypass switch will work, but it defeats a LOT of the protections of the EMS unit. The bonding plug is so cheap and easy, there is absolutely NO rationale for defeating those protections. Generators do fail on occasion.
