Absorption fridges are somewhat of a joke, but if you do any boondocking, a residential unit really isn't a good option. My last camper had a 6 cf fridge and now we have the "4 door" 12 cf. The 12 does a good job, but it needs a little bit of help on the really hot days. I have installed 2 of the 12v dual fans that are rather affordable on ebay and the air circulation all but fixed the temperature issues. You still need to manage how often and how long you have the doors open on really hot days.
It is still a compromise with any absorption fridge when you are looking for things to cool down fast. I have a hard time convincing my wife and kids that they can't come home from the store and stack 20 warm water bottles in the fridge and expect it to cool them down.
