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

I'm not a fan of the Molly "system." The torque needed to "set" them often
exceeds the friction against the drywall board.
The very simple plastic sleeve works much/most of the time.
My favorite is the plastic anchor that has wings that pop out when you seat
