My TT had NO counter space.  There were inches around the sink and stove and a board that could go over one of the double sinks.  I needed to do something about it.....Here is my solution!!!!

The original counter space

I'm guessing I just increased my counter space by 80%

I hinged it so I can fold it when we open the couch for sleeping

I used folding leg supports to support the table when open.  I used 4 typical hinges where it connects to the existing counter.
