found it!.....the below link looks like the one I altered. And, because it has a base to it I did not need to mount to the wall. I attached it to the sides of the bench and corner braced it to the floor. There is just enough room for the electric box to open...However, there's only one problem with size...you still have to squeeze by on the bathroom side of the trailer when the table is up and it's pretty tricky to set up the table when sitting on that side....but we love the extra space. And I plan to get some custom pillows to make a small bed...one day!
