Since I like to lay down at night and sleep like a baby, I would install some backing. I don’t care if some “thing” in drywall is rated at 250 pounds or not.
You tellin’ me you want to put a toggler into the wall and you hang yo 200 lb. plus tail off it?
It’s drywall.
There is no truth anymore. Only assertions. The internet world has no interest in truth, only vindication for preconceived assumptions.
