Oh, you mean all these glue lines :-(Aliner has a production video which shows a crew gluing and screwing the cabin box to the frame. There are only a few mechanical fasteners holding the box in place (my trailer has four), but plenty of glue. The difficult part of removing the box is separating the glue lines that hold the floor in place on the frame beams. No matter what method is used, it will damage the floor.
Dynamite is a quicker option.My Hilti vibro hammer and spade bit will handle the glue lines
