My parents just bought a new Winnebago(or one of their brands) they swapped the couch/bed for two recliners. They did a lot of research, dimensions, material, base, tiedowns and even sat in a few at a Good Sam Rally. They are very happy with the recliners. I don’ t have the brand name of the recliner but they are out there(if you need a brand name let me know).
Here is an interesting side note: it would have cost $300 extra to not install the couch at the Winnebago factory. They had the couch taken out and chairs put in at the dealership, then sold the couch on Craigslist.
