Forest River uses a VESA mount behind the flat screen TV that should lift up and detach with part of the mount attached to the TV, and the other half attached to the cabinet. The problem I had with this, is that the bedroom TV mount was connected so tightly that it would not easily separate. I ended up reaching behind the TV in the cabinet and unscrewing the small piece of plywood that attached the VESA mount to the cabinet. Note that the Georgetown uses Robinson Head screws for much of the cabinetry, so you will need the correct screwdriver.
The living room TV looks like it would have to be removed the same way, as part of the cabinet fits over the top of the rear of the TV, preventing it from lifting up and off the VESA mount as it is designed to. I have not had a reason to try and remove the living room TV, but someday I might, as part of the cabinet blocks the second HDMI port on the back of the TV.
