Open ground detected
Searched the forum and was surprised I didn't find anything on this topic. We are taking our TT on our first boondocking adventure next week and wanted to test out our new Champion inverter/ generator...

Normal for most generators to be open ground.

Modern generators (<10-20 years old), yes. Older ones were bonded.
Neither of these generalized statements are correct, as IAMICHABOD's own example illustrates - his particular Generac is an inverter suitcase style of genset which the manufacturer has chosen to offer with a G-N bonded output ... most other inverter style gensets (Honda, Yamaha, Champion) are not G-N bonded. Each manufacturer has their own preference as to what would be the most appropriate wiring scheme for the greatest number of consumers. The only reason "older" gensets would have been bonded is that most decades ago were open frame, construction type of gensets which traditionally have been G-N bonded.
It would be more accurate to say that most inverter genset's sold today are wired with a floating neutral output while most open frame, construction types of gensets are still wired with a G-N bond. Regardless, if you're feeding the trailer directly either wiring scheme will work just fine but if you're using an EMS between the genset and the trailer the genset output needs to be G-N bonded, whether wired as such by the manufacturer or forced by adding your own G-N bonding plug.
