Welcome to the forum and potentially to Keystone RVing.
The Sprinter 316BIK is out of production. If you go to the Keystone website at:
http://www.keystonerv.com/sprinter/
You will see the annotation of "STOCK ONLY" after the model number in the floorplans. That indicates that the only available units of that model are at dealerships or being transported to dealerships.
That may not be "bad news" for you, because Sprinter is stopping production of nearly all their models and starting production of the Sprinter Wide Body models. There is a new model available, the 316BIK-WB which you might find even better for your family.
Good luck with your RV shopping and if you've got any specific questions, just post them and you'll probably get answers from the membership here. There are two members who were looking at the 316, but I'm not certain if either actually bought the trailer. You can do a search for 316BIK by using the search button in the blue bar at the top of every forum page. Hopefully some of your questions may be answered there.
Again, welcome to the forum, make yourself at home.
