Not sure if it’s safe to put a screw in the wall? Me either.
However, I was able to grab some photos with dimensions when i was fixing the outdoor outlet. You’ll note that I wasn’t being careful so one of the photos is in inches and the rest are in millimeters. I’ll convert both ways:
The full wall is 1.35″ or 34mm. The inside panel is 2.74mm or .11″. The outside (Azdel) panel is .17″ or 4.39mm. The most important part of this is 1″ screw should be safe to use when you want to hang something on the inside of the trailer.
I had pulled the valences from over the windows and have been reusing them when needed. They’re 1″ so we have that as confirmation.
These screws from Amazon match the ones I removed from the valences.
