Use a small inverter to power ice maker
My 2007 34 came with an ice maker and through-the-door dispenser. Unfortunately, WRV did not provide a connection to the inverter so it doesn't dispense ice or water with no 120 VAC. Some people have run extensions or otherwise provided AC from the main inverter but I think it is simpler to put a 200 watt inverter in the reefer compartment and plug the ice maker into it. These small inverters have cigar lighter plugs so I wired a female to the 12 VDC. Now we have ice and water when dry camping or going down the road. Warning! The reefer has 12 VDC even when the main switches are off. Next project, wire a switch to disable inverter when parked and install a filter on the water line.
