Sorry to hear about your problem, but frankly, the problem you describe is not unusual.
First, I find it difficult to believe that Ford would have outstanding payments due to a dealer for an extended period of time if that dealer had done everything required of them to get payment made to them. I have been in the business for over 40 years and normally, when you see a problem like this, if you trace it back you will find that someone dropped the ball in their warranty submission.
As for getting service, all I guess I can say is join the club. You think getting service on your Ford chassis is difficult? At least in their service network, they service all parts of the chassis and drive-train. Try a diesel chassis, where you might have to visit an Allison shop, a Cummins shop or a representative of the chassis manufacturer itself for all of the different components. The nearest service centers from where we live are well in excess of 200 miles each way. Get to drive the coach to them, leave it for repair, drive home and then go back and pick it up when it is finished, hoping that they actually fixed the problem. Sorry, but just the way it works.
Safe travels.
