Welcome to the forum.
If nobody here is able to answer your question, I do know that Forest River/Coachmen used to have pretty good customer service when contacted at the factory. I'm not sure it that's still the case or not but you might want to give it a shot.
You can email or call and hopefully, somebody there should be able to help you ...again, if nobody here on the forum can:
