Be careful drilling and I recommend using a really small drill bit to ensure you found a stud. If you look at some of the FR sales literature, you will see the trailer does not have a traditional house frame with evenly spaced studs, it is more an outline of the side wall with a couple supports at certain places. My salesperson told me that there was a stud where the wall paper crease was. I was trying to install a set of steel cabinets. I figured once I got through the steel, I would hit aluminum, stud finder said I was good. nope there wasn't a stud and as soon as the drill got through the steel, it went right through the side, it went through the 3/4" foam immediately. So I had to patch a small hole, there was a stud but it wasn't anywhere near where the sales person said it was.
