I am installing one of those MS SS 300W PSW converters. I will be using a separate 120V outlet.
I can't see why I would want to connect the AC ground to the frame because it cannot go to ground unless I am plugged into shore power.
Same for the DC ground. I have bench run several tests without any grounding from the inverter. Why do I need to use the ground to frame at all for a totally isolated system that is only connected to battery + and -?
I have a few devices I would just like to leave on the inverter for simplicity.

I guess you may be referring to the fact that I mentioned that the green ground connection on my 30 amp female receptacle fed by the inverter that I plug my shore cord into, is grounded to the frame. So is there any downside to grounding the receptacle to the frame? Or does it just not make any difference whether it is grounded to the frame or not?
I don't see any downside to grounding the receptacle to the frame. Just make sure you have the 4ga ground wire from the Suresine grounding lug to the trailer ground. 4ga seems excessive to me as 6ga is normally all that is required, but it never hurts to follow the manufacturers recommendation.
