And he finally got an answer to the question!! :C
By RVIA definitions (as followed by RVNet), the Unity (Serenity and Libero) are all Class C because they are built on a cutaway chassis. LTV had always correctly referred to them as such until they were purchased by Triple E. Then Triple E, who had been a builder of more traditional looking Class C units with the over-cab beds, made the marketing decision to use the salesman terminology of "Class B+" even though none of these units are Class B's.
I always give them a hard time about the use of this marketing term whenever I encounter anyone from the factory at a rally. :B
