Finding the same original wall board has not been easy. Often not doable. I have some for my year camper (2004) but I acquired it from a damaged camper someone was selling for parts years ago. I have not run into anyone yet who has found a supply of original wall board.
However I am rebuilding our T1950 (Project camper no. 1). The entire back wall and some of the siding wall inside is gone. The plan is to buy 1/8" luan plywood and then use commercial grade wallpaper (ideally vinyl paper in our case) and match it as best we can. I may have to redo a good wall with the new pattern just so it all matches.
Others here on the forum have gone the commercial wallpaper route too.
