We just purchased a Rockwood 8265s 5th wheel. It doesn't come with a swivel rocker chair in that floor plan but we think it's room for one next to the couch slide. Ours has the slate interior color. Would it be best to try to get one from Forest River or try to find a small one at a local furniture store that would match our interior. When shopping for a trailer, I notice that the ones in the trailers that did come with the swivel rocker(s), that the chairs wasn't a perfect match to the couch's in those units. So Forest River must purchase a generic flex steel type chair with a color that's the closest match to the couch and interior colors.
I removed one of our rockers from our 8314 and bought a small recliner, the interior in our camper is slate as well. The quality of the recliner is better then the rocker from Forest River. My camper came with two rockers and I had to repair one of them, the chair part of the rocker came off of the swivel. I think we bought the recliner from the Room Store last year. The recliner is approx the same sizes as the rocker in width but the back has a lower profile, which is good because of the large window in the rear.
