Heartland and DRV

Let me re-examine a closed thread. I recently requested a brochure from DRV and observed that the East Regional Sales Manager sent it from a @heartlandrvs.com email address. When the thread was closed in 2015 it was my understanding that the DRV brand would remain completely separate. If the email is a Heartland email, what else has been incorporated into Heartland?
