Just check for anything that may not be able to be removed. When I removed the dinette in our Minnie trailer, there was a small box covering the opening where the 12 volt wiring came through the floor. Fortunately, it was close enough to the sidewall that I could remove the cover and leave the wiring as a small cabinet was installed next to it and a Flexsteel couch replaced the dinette.
When I removed everything, the walls were not a problem. Typically, walls are finished before furniture/cabinets are installed.
Good luck!
