the real question is one of understanding that if you want a 'whole house' inverter wiring within your coach, you will need the inverter to only power the circuit breakers that are wired to each outlet you want to power from the inverter...meaning that you must use a 'sub panel' for those breakers, so that the incoming power from the inverter is only providing output to those breakers, as a whole... usually this means switching out your current Electrical Panel with one that can provide an integrated sub-panel, or added a totally separate sub-panel, which would require some additional wiring, and a lot more work.
You can't really just 'install' or add a whole house Inverter if your unit did not already come with one, and already wired correctly to the main panel... there will be a lot more work involved than the simple addition of the inverter.
