Honda 3000is powering a 1999 American Tradition

I wonder what this "yellow adapter" is that everyone has :)

I wonder if the OP can plug his into both the twist lock Honda 30a receptacle (good for 23) and also the 30a campground non-twist lock receptacle.

I wonder if the shore power from either if working ok, can supply the air conditioner but not pass through the inverter to run its charger component.

Which leads to the question just what 120v items the OP's inverter/charger does supply via sub-panel or main panel whatever it has going on.
