Based almost 100% on a series of posts here by OCD (I think!), we replaced our aging Norcold (Nevercold) AC/DC with a Summit 10.7 (approx.) cu. ft. apartment-size fridge freezer. We couldn't be happier! It's so much better insulated. It has so much more space. It makes big, solid ice cubes in just a few hours. It never needs defrosting. NEVER!!! And although it's AC only, and has to have it's electricity inverted, I'm sure it uses less power. It easily runs on 4 x 260w solar panels during the day (along with the 8 golf cart batteries being fully charged by the end of the day.
At the beginning of a long time away from Costco, we use a 12V Dometic "cooler" that can be set to fridge or freezer temps. Once we have room in the Summit for all the food, we just unplug that one.
