Just following up on this. My r-pod was in storage for a few weeks so I didn't get a chance to do anything. The video was key on the outer walls. What I found was that the instal at Forest River was off by a small amount and basically missed the metal frame in the walls. Now that I know where to look, the fix was trivial.
On the dinette window that is on the arch one the rear of the trailer, that appears to be wood in the walls at some unknown spacing. The screws that Forest River used were self tapping which implies that they were supposed to hit something other than paneling. After putting a few tiny holes to locate the studs, I found that FR again was off by a quarter inch in all directions and missed the stud for the blinds and the valance. Again easy fix once you know where things are in the walll.
I expect all the blinds and valances to fall off eventually if I do not proactively go fix them. Thank you both for your insight. very valuable.
