I sent you an email with the diagrams that I have for the 2008 210WBS framing (outside walls). I don't know if there is any provision on this forum for the posting of documents and if I "imaged" the files, they would be too small to be of any use... The interior wall is wood framed, as is the roof and parts of the floor (it is a "mix" of steel and wood) and only the outside walls are aluminum framed. A good stud finder will find the studs in either type of wall framing for more exact locating of mounting points.
Hope they help
