I like the RV type fridges since they do not take any electricity to work. That makes the batteries last a lot longer between charges. However, I like most on this list do not like the price or trying to figure out how to get it vented. In my case, that is just not an option. Since I already have a dorm size refrigerator, that is what I will use. I had looked at the models with the seperate freezer, but decided to stay with the one with the freezer in the same compartment. The reason is that I will be filling the freezer with blue ice packs. That way when the refrigerator is plugged into 120v ac, it will freeze the ice packs so that when the power is off it will act like a cooler without the melting ice (water) mess. If you shop around, you can find the ice packs pretty reasonable. Once the refrigerator is plugged back in, then it cools the inside and re-freezes the ice packs. It should be good for a couple of days without power this way. You could also use containers ( bottles of water, lock-n-lock containers etc) instead of the ice packs. We also rarely take anything camping that we need to keep frozen. We also rarely need plain ice. If the need arises, then we will just take one of the small 5 day coolers and put ice in it. Anyway, thats what I plan on doing.
