David, you're right. We're a small segment (not even sure if my little VW EVC qualifies as a "Class B").
Not smug. When we are camping we just always enjoy people's stories of how they got started RVing, what they drove in the past, what they have now, what they like/dislike, mods they made. Always interesting stories.
Yes, not many Class B's out there. From RVIA study of wholesale units shipped 2007-2014, RVIA's numbers indicate only 3000 in 2014. RV Business reported in April 2015 that Winnebago had a bit more than 30% of the RV market. So that's about 900 units per year for Winnebago and that is made of 2 Class B lines, ERA with 3 floor plans, Travato with 2. Not big numbers to get the volume to keep prices down.
Of all the Motorized RVs and Towables, Class B is at the bottom, even behind Truck Campers. Trailers lead the way with over 200,000 units shipped in 2014.
