Slide out galley?

I searched and did not find any posts on building the galley where the entire unit slid out (please forgive me if I missed it), not just a cabinet.
The idea I have is this, we have an old, old tall beagle who likes some room. I'm trying to keep the TD length to 9 feet. I plan to build a dinette/queen bed running lengthwise. This would not leave but about a foot of floor space for dear old Max, which he would not like. I also looked at existing designs and thought that one needs to stretch a bit to reach any upper cabinets in the galley. My idea is then to build the galley essentially 2 feet deep. Bed is 6, galley 2, that only leaves a foot to spare maximum. With the full slide galley it locks inboard during travel and can be pulled out like a foot when parked. This adds floor space and conceivably makes the galley easier. It would be like having a 10 foot trailer when parked, 9 foot when rolling.
I would build an internal "framing bulkhead" for lateral stress and for the galley to lock into. I have some super heavy duty drawer slides which could easily handle the weight, but I think I could do it better using bearings since it wouldn't actually come all the way out of the trailer.
So, has anyone done something like this? What problems am I missing?
Thanks in advance, Dave
