What I would suggest (to accomplish what you're trying to do) is putting the receptacle in the compartment with the inverter, or most likely use the one on the inverter with an adapter for the 30A shore power cord, and then install a standard RV cord compartment door with the "mouse hole" in the storage compartment door. When using the inverter, snake the shore power cord through the mouse hole door in the compartment door and hook it up. Nothing is exposed to the weather, nothing is too hard to wire or install, and it all looks reasonably decent.
