Most people don't realize the way these trailers are built. The metal is the last part to be put on, so if you need to replace the ceiling or a wall you will have to remove the metal.

You could probably use the frame, windows and maybe the metal siding from the trailer in the photo. The rest would just be a pattern for building a new trailer. That's basically what I did on the '53 I rebuilt a few years ago and it was a lot of work. here's a before and after.
