Welcome -I can't be of much help either regarding the TV mount as we don't use one. My TV is actually my sticks and bricks bedroom TV that we bring along and then return to the bedroom.
My TT indicated the place to put the TV mount, so I assume that the one that can be ordered for my Sylvania would work. Just placing it on the wardrobe works for us. We mostly use it for the over the air local weather channel when we are going fishing.
