I believe #501 was the 1st number DRV used when they started buildilg mobile suites. I had a 2004 mobile suite and have followed this site for many years and I believe # 501 was back at the factory numerous times and the factory put updates at no charge onto that unit. The next person that visits Paul Cross at Indiana interstate ask him for some history. I have a visit scheduled with him mid October.
