I think you'll find a few more than that, after you get into it. There should be screws holding the fridge to the floor, screws holding it to the cabinetry (and vice-versa), and screws holding it to the inner shell. Most I've seen have about 18 screws holding the fridge to things. There will also be 120 volt, 12 volt
, and LP connections. Take photos of the dismantle process, so you don't get halfway back together with it, and be scratching your head over where the extra pieces go.
Something "extra" to consider while you've got it apart, is adding a 12 volt
muffin fan, like you'd find in a computer, to the back of the fridge area. Some trailers already have them, if yours doesn't, I'd recommend one, with a switch so you can turn it on and off. It will help the fridge keep its cool on hot days.
