I have a good friend at church that has a 1972 Fleetwood 7523? It has cloth seats front and back and jump seats. It's been stored for years (as long as I've known him) in an open front shed. He says it's 99% complete. I've never wandered over to the shed when we have our annual chili supper in his back yard, so I can't supply further details.
If you're interested, send me a PM and I'll give you his name and phone #. I know he'll be away this weekend on a MS bike ride. Last Sunday, he said he'd go out and get some pictures of it. We are in Mid-North Indiana.
