Mobile homes (not RVs) have this pathetic, thin board stuff for walls. It won't even hold a sheet metal screw.
There are so many anchors available for drywall, but which is best for this type of wall? (Trying to mount a 5-foot x 1.5-foot mirror using 6 plastic edge-grips.)
Suggestions? (Extra points for URL to show an image of the type you're referring to...)
Thanks,
