Here is one of my best accessories when traveling in my RV. This cooler/freezer will freeze ice cream and keep all your drinks ice cold. It's about 40 liters in size and it eliminates using up space the in general rv refrigerator. It comes with a 120v plug and a 12v plug adapters. I can leave it plugged into a 12v outlet in my truck or in my RV. You can also when traveling between hotels it comes in handy to bring into your room for keeping drinks and leftovers cold. It appears the unit is no longer available on Amazon but there will be other brand available. Expect to pay in the $200 range. https://amzn.to/3Nb5XIx
