The quest is over!!!!!! We finally found a used RV sofa for our 1971 Airstream. I had been pricing Flexsteel sofas at Camping World and on ebay and could not believe the prices-almost $700.00. The cost of RV furniture is astronomical! I was lucky to find our sofa on Craigslist, which is a free for sale ad site. I paid $200.00 and it was located here in Las Vegas. It is a folding (like as jackknife) sofa and is brand new. The sofa came out of a new RV. We had looked at a purchasing a futon sofa (would not fit), regular sleeper sofa (too heavy and most too big for the space). We were going to recover the old sofa but it was beyond repair, frame broken, springs shot.
