Use your on-board charger. If your camper didn't come with a 30A to 20A Adaptor get one. Plug your camper into an extension cord using this. Do not use the A/C or microwave while using this adaptor on an extension cord.
If you are concerned with overcharging disconnect the battery at the disconnect switch. This switch could be mounted to the tongue frame or inside the front pass through storage. Follow the + battery cable to find it. The camper retains power yet isolates the battery when this switch is off. I turn mine on Friday night to charge on the weekends and turn it off Sunday night.
This is a great idea. Leaving it plugged into my 30A outlet is most likely ok as well.
