Hey SpeakEasy, good luck with your planned installation. Because you reference a "clean" installation (a man after my own heart) may I offer some additional information that may be helpful. If you plan to install it in an interior hollow wall as I did you may be able to cut the opening using a jig saw. However, when I tried this it worked fine at the beginning, but I discovered there was a wire inside the wall that was in danger of being cut. I switched to a utility knife for the remainder of the cut. The camper walls are so thin that I actually got a nice clean cut with no difficulty. The only additional recommendation I have is that you make the hole as accurately as you can to ensure a nice snug fit. There are little plastic tabs on each end of the monitor that will compress when you insert it and hold it in place. So a sloppy fit might not hold very well.
