I too have the same issue. Just purchased a new 2014 295BHS and sold my 2009 235RKS which was bought new but needed more room. The other day I installed tv mounts for the main bedroom. It had a solid 1x4 behind the wall to attach the mount too. However as for the bunky wow, it is not made to attach any mount to the back. I still pushed foreward and tried with the butterfly or winged screws. Seemed to hold however I see to much movement or lack of support. May have to try the ply method to the back. You would think this would be already provided?
I am new to this. This is my first post but not new to Surveyors. Really liked them a lot, which is why I purchased another one.
