It's relative, the market share for B's is very small compared to A's and C's. you may think you see a lot but it's a very small percentage. B's are also very unique. Most A's, C's and even TT's share a lot of the same components and build methods. B's are in silo as to how they are built and the materials to build them. They are also have less issues due to how they are built and the cost at which to build them lends better support. By comparison, there are a LOT of issues with production C's and A's and most folks come on here to address issues. Probably over 98%. It's pretty rare someone on the A forum gets on to talk about how their coach is flawless. All you see are problems after problems. Fewer B's and fewer problems with them mean exponentially smaller forum activity.
