I purchased a 2014 Sanibel in November of 2013 but it was classified as a 2014 model. I was told by the Dealer that the RVs are like Cars they change tooling in September or October each year for the next year production. By my date tag my Sanibel was built in October of 2013. It looks the same as 2015 Models with only minor changes.
All in all, I like what I purchased and happy I bought a Forest River product!
