Gene in NE, Sorry I haven't taken time to answer you . No Pictures yet so I will try to tell you how I solved our problem.
first removed the kick panel under the couch. Then our good dealer supplied me with a piece of 4" x 12" heavy foam rubber the length of the couch. Also he ordered matching upholstry material from the factory for me.
I cut a piece of 3/4" plywood for the backing & covered it with the foam & material. (easy job)
Then I made three supports out of 1"x1" heavy wall pipe for holding up the extension. The supports I Hinged a leg on to reach the floor & a cut out notch to fit the existing 1x1" rail under the couch.
When the supports are in place the 12" extension sets on them.
I had to build up under them to match the height of the seat cushion.
I removed the "hooks" that fastened the original kick panel & re attached them to the back of new Padded extension.
When the couch is in the up position the ext. fits nicely under the front & does not interfere with the slide out operation.
I also installed a hinged "table" 6" by the length of bed & extension on the slide out trim that I fold down when in the bed position. This becomes an extension for a pillow when we are sleeping. (no padding needed under the pillows)
I hope this explains somewhat of how I did it..
We are leaving Sept. 13 on an extendet trip thru South Dakota, Wyoming, Utah, Arivona, New Mexico & back to Texas.
