I've been told AC always needs an earth ground, DC not.
Strictly speaking, this is incorrect. The earth ground is actually a safety ground, and not required if you have ground fault interrupters.
"It's against NEC code for the trailer to have neutral and ground bonded together." ....and yet all trailers do?? Morningstar requires it for their inverter? What do they say?
First, no RV has neutral and ground bonded- the only place it will be is if it has on board power source. The inverter is a power source, as are generators. The neutral and ground are bonded *at the source*, but when you disconnect and go to shore power, they must be separate.
