Here is the bunkhouse TV Mount. Followed the same process as the front TV mount and used the same screws.
Started with my famous double-sided tape and pilot holes.
Secured to wall and TV mounted.
Fully adjustable depending on where the kids are sitting at.
Here it is pushed back into the cubby.
It is not a latching mount, but I got the idea from someone else here to use an adjustable shower bar to hold it in place. This mount is actually pretty stiff anyway. Got it from Amazon for about $15.00.
