Thank you for choosing Pioneer!
When Heartland makes a brand specifically for a dealer (Camping World etc.), they are very close cousins to an existing Heartland product, yet they are custom brands for the dealerships. I can't say for Pioneer, but often times these units are serviced and warranted by the dealerships as a private labeled product. In these cases, we don't generally create special sub-forums for them. Rather, we encourage you to post about them under their cousin brand sub-forums.
I'll check-in with Corporate to learn more about Pioneer. If it warrants its own sub-forum, we'll gladly make one for it.
