It sounds like a lot of folks earlier (like 2 yrs earlier) on in this tread were having their Rv seats replaced with seats from some of the actual RV seat supplier, Lisa had mentioned using BMW seats, while I agree they are comfy - I don't think they would look quite right - maybe too sporty looking. I am pretty sure their seats are Recaro (at least in the M series cars). So they wont be cheap to buy or re-upholster. I just wanted to share what I thought was a great find. I recently swapped out the seats in my class C with seats from a Honda Odyssey. They are SUPER. They are very adjustable and comfortable , and the right size. They look correct in the RV as well. The seats have very level bases - which make it very easy to mount to the original pedestals (w/some flat bar). I used the divers and passengers which have some very cool storage type armrests, they are power and heated. My RV has two rear captains sets which the odyssey has perfect seats for that as well. (rear seats are captains in odyssey). The best part was I was able to get the whole set in leather for less than $200 at a local junkyard. It seems the odysseys are plentiful. Mine were out of a 03'. I have seen them online for more than that, but best investment if you are looking for take-out type seats. I was looking for the seats out of a Toyota Sienna, the later model have rear captains with leg recliners. They are available, but out of my budge. Funny thing is that there is a company in Indiana that sells them as new take-outs on Ebay. I think they are coming out of handicapped modified vans, as the plant is there.
Just my 2 cents, thought I would share my experience and success with used seats.
