Yes, we did the work ourselves. By reconfiguring the floor plan, we seemed to have opened it up a bit, or at least it feels more open. We took out the goucho along the street side and built a permanent bar/dinette with two folding "leg-o-matics" for seating. This was a simple structure made of 5/8" plywood attached to the side wall and closet wall on one end and the old dinette leg on the other. Covered it with linoleum and used an aluminum edge trim.
We completely removed the front dinette as it was difficult to make up and take down everyday and storage was less than handy. In its place, we built a wood frame over the fresh water tank and attached the goucho framework and slides (including the dropdown door) to create an oversized bed/lounge (with storage underneath) that takes up the entire front 48" (almost to the door) and pulls out an extra 16" for sleeping, making a bed larger than a queen. I attached a 16" piece of 3/8" plywood to the sliders from the goucho. To slide it in, I just pick up the front edge of the plywood which is attached to the frame over the water tank (it lays loose over the sliders) and push with the knees - easy.
We had to special order two chunks of latex foam and have it covered at an upholstry shop -- expensive, but very comfortable. During the day the bedding gets rolled up to the wrap window, the 16" foam cushion flips up to hide it, creating a lounging couch. At night, just pick up the front edge and pull out 16", pull the cushion in place and unroll the bedding. Takes about two minutes to make up or take down.
