I have the dometic CFX3-35. Purchased a few weeks ago when I bought my Grenny. I will have to say it is the best purchase I have made for weekend warrior camping. I use a combination of the Grenny battery when driving and have a Jackery 1000V2 that I use when I am off grid. The Jackery to me is equivilent in value to the fridge. Together, with a solar panel, can run as long as needed off grid. One of the unintended consequences and totally a first world problem, is that I enjoy a cocktail at the end of the night, and not having ice is a bummer. I have a yeti tumbler that I now load up with ice before I leave the house and can get a few mixed drinks worth of ice for 2 days lol.
