No, the decal on the front of the Scotty teardrop (Sportsman, Jr.) is not accurate. They didn't use any decals on them and even after they started using decals - in 1961, I believe, that decal was not used. That decal was used on the front of Scottys later on.
The 13' HiLander isn't a myth however it was just a 13' Gaucho inside - it wasn't the HiLander interior. No one seems to know what happened to it, but many folks would love to have it.
Kevin - yes, the Rear Door is still at the RV Museum - I have pics of it here:
