Welcome to the Jayco Owner's Forum, and congratulations on your new trailer. "New" just means not previously registered. I purchased my new 2013 Eagle this January, and they're currently making 2015's. There are a lot of new 2014's on dealer lots, and you can still find a few 2013's if you look hard enough (as you found out).
Hope you enjoy your new camper for many, many years!
