I have a 1000watt inverter/charger on my boat. My choice is to hardwire the refrigerator and one outlet to the inverter. This requires removing those circuits from the normal distribution circuits so they do not feed back or get confusion from the 115VAC panel. When the 115 service is available those circuits revert to that service and when it is disconnected they are switched to the inverter. I have checked the change-over time using a digital clock plugged into the outlet and it does not notice the switch, probably less than one or two cycles. The big advantage is charging when on shorepower BUT with the camper you must determine which battery(ies) to connect to the inverter/charger since the camper's converter/charger will be drawing and charging as well and you don't want competing systems. If your inverter is only outputting 115vac and not charging this may not be a concern. Check the manual!
