The fridge in my truck died last month. I replaced it with the same model from WalMart, (about $125), and except for asking a couple guys to lift the new one onto the passenger seat, was able to remove the old one, and install the new one, all by myself. :7 It's a pretty good fridge, IMO, I wouldn't see any reason to spend a lot more for one.
PS What looks like a butter dish, is actually an ice cube tray, lol.
