We had a wine rack installed in our 2007 Dutch Star. We had some custom cabinetry done and it was part of that work, so I don't have a price for just the rack. I'm attaching a picture that gives you "most" of what it looks like. The top rack only hold 3 bottles, but the larger bottles. There are 4 racks below that hold 4 regular bottles each, so 19 bottles in a pretty tiny space.
This was done by Irv Kaufman in Nappanee, IN, but he has since sold his business to Gene Miller who has also done some very nice work for us. If that interests you, I can provide contact info. Before you ask, no....we have never had any issue with bottles escaping while driving. That's even on some VERY rough roads.
