That is surprising. We have counted trailers versus motorhomes before but not Cs versus As.
It's possible the Cs versus As may be influenced by time of year. I would guess that Cs are more popular with younger families that may travel more during summer, while As may be more popular with retirees or empty nesters who may travel more after the summer. When our children were home we vacation mostly in summer due to school, but now travel more in Fall and Spring.
It's also possible that the area of country may influence results. Places like Florida with more retirees may have some bias towards Class As. Just a wild guess though.
