So after doing some thinking, and not wanting to have to cut up and redo our entire front bunk, I came up with this basic plan for a fold out table that will not be huge, but should be large enough to be useful... here is my photoshop plan...
we are still waiting for the weather to cool down so we can stand working inside the trailer. The basic plan is to cut a shelf board to be 16" x 16" which is the max size for the clearance it needs to fold up and not get stuck on the bench cushion. We decided on 16" wide, so there is plenty of room to sit down on either side of the table once installed and opened up for use. We will be mounting it to the front wall with 2 folding shelf brackets I found on line. I will post updates once the actual work is complete.
