However it is true that when you are not plugged into a properly wired outlet,, Yes, then they are not bonded. This often includes both Generator and inverter power.. They may or may not (usually not) be bonded. My inverter is bonded if inverting. Not if Generator is in use.
But the RV is a "Sub" panel off the park main, and it's the park main where the bonding happens.
For a built-in generator in an RV, neutral and (chassis) ground should be bonded together per the NEC, as I understand things. If it isn't, then the installation isn't quite right. On my motorhome. they are indeed bonded at the generator by having the ground and neutral leads from the generator connect to the same star-shaped connection doohicky on the generator chassis (which is also where the 12V chassis ground return line is connected).
On a (small) portable generator, neutral and ground are generally not bonded together, I suppose because sometimes these will be hooked up to a household electrical distribution system and having two neutral/ground bonds is to be avoided.
