We have a Raritan Icer-ette that we never use. It requires 110V meaning that we would need to run the inverter just for the icemaker. I guess we could dedicate a small inverter. Instead we use ice cube trays in our 12V frig/freezer, and if we see a need for larger amounts of ice we put more trays in our separate 12V freezers. The freezers are about the same size as the Icer-ette but offer more versatility. They can be loaded with ice cream, and other critical food groups, in addition to plain ice. I suggest you check out a 12V freezer before you commit to a dedicated ice maker. Then also consider whether you will have 110V available all the times you want to make ice.
