New model Bighorn avaliable when ?

In a new model year what month are the Bighorn trailers avaliable at dealerships.
Thanks

We Ordered our 2009 in December of 07 and it was delivered early March of 08. From what I understand they show the new models at the Kentucky RV show in the fall and production starts then or soon after.

We were told by our dealer that on last Oct 31st they stop making the 2009's and began producing the 2010's. JimBo should know the real answer. These do not include the units like mine that were stopped early, and were replaced midyear by the Bighorn 3410RE.
