There was a recent exchange in a thread (2air' on one end) that had some of the infrequent inside skinny on this topic -- and there was still disagreement over what it meant. Otherwise it all falls into the black world of proprietary information, business secrets, etc.
Not that I have the totals, but when I was going through the factory tour the 19' and 25' Safari units were the most popular (in whatever config selected base Safari, CCD or SE). Since the FB units came out in a 27' and they are avail in Classic, I'm not sure those numbers are still true.
