Update on Design:
The flip up bench extension seems to be impossible to engineer the way I want it. I consulted with my DW and she can up with a similar fix to Gary's bed extension. Some kind of hangers like Gary used, and the extension will be stored under the bench. Going to get Ms. 213 in a couple of hours and begin!!:@

OK, she is home. I have an electrical box between the water tank and the exterior wall. I need some of that distance for my couch/bed. Can I mount the box on the wall?
:S
AND, can I put screws in the outside wall for mounting cleats? I see that the present dinette uses them now.
