The only connection between the gens and the inverter will be that the batteries will be being charged through the trailer inverter while the gens are running. Does that make sense or am I just making it more complicated?
It is still not clear that when you are on shore power or generator, that the TV etc will not be powered the normal way instead of by the inverter, and that the inverter output is not tapped into the RV 120 receptacle circuit somehow.
If it is, AND you run the inverter, they will get two doses of 120v at once and fry who knows what on 240v. That is what a transfer switch is for.
You can run just the TV etc off inverter. You must not tap the inverter output into the regular RV receptacle that the TV is plugged into. The TV has to go into the inverter output directly via an inverter receptacle (perhaps extended as needed)
