Hey guys, I have a 2021 21RBSS. My TV mounts to the face of one of the cabinets. My question is, does the backing plate cover the entire flat face of the cabinet, or is it just a certain size centered in the cabinet face ? The entire front feels very solid, no give to it at all. I was going to mount my TV mounting bracket, but didn't wanna start drilling holes until I was certain where the backing plate was.
