Is the year of the coach based on the year of the chassis

Thanks for the responses. After reviewing all the paper work there was a MCO in the packet. It would have been nice if the dealer would have brought that to our . We signed for it in January and took delivery yesterday on 4/24. It never dawned on us that ordering something at that point in time that they wouldn't match. It makes sense after having it explained. Still not happy with how the dealer didn't explain it to us up front.
