Never tried the Dorm fridge. I did have a 12 volt cooler for drinks. Cooled them some but not to my liking. Currently have a cooler and an ice maker in the storage compartment. This has worked out rather well. When on the road make ice overnight to stock the cooler for the next day. When parked for extended periods it makes enough ice for the cooler as well as some to stock in the freezer for drinks. You probably already have the cooler. Ice maker is around $100. Also use the ice maker at home to fill the freezer with ice for various uses.
