Make sure shore power and inverter power cannot see each other. I've seen installations where individual relays paralleled breakers right at the main panel.
Physically plugging the shore power cord into the inverter, as the original poster was suggesting, is of course one foolproof way of achieving this. It is not the only way, naturally.
More generally, there should never be any way of having two sources of AC power connected to the same circuit simultaneously in any RV. The only exception I can think of, if you want to call it that, are inverter generators which are designed to be able to be paralleled, in which case the parallel kit does connect the two outputs together and special circuitry in the generators allows them to properly sync up and share the load.
