This is the mount that came with our 17 39 MB, we have the storage as well but this one can pull out and swing in both directions. If you notice there is a clip on the shelf that the tv snaps into to hold it in place and there are straps added for travel. i searched the mount for some identification (manufacturer, model number) but couldn't find anything. Don't know if you have a wood face on the side of the storage to mount this type or not, but it might be an option. You might call RW and see if they cab provide info.

There you go! that's the one you need Steve.

Here is some pics of my TV mount.. as you can see, plenty of storage, and the TV swivels both directions...

Here's pics of the mount installed by RW service to hold the new tv mount
