Hi nvarallo,
Welcome to the Heartland Owners Forum and to the family. We have a great bunch of folks here with lots of information and all willing to share their knowledge when needed.
I have never heard of any of the units coming with 2 DVD units. So I think it is just a mistake someone made in while distributing the paper work. I'm sure some of our other members will jump in soon with more info.
Be sure and check out our
Heartland Owners Club. Join us at a rally when you can and meet lots of the great folks here and make friends for a lifetime.
Enjoy the forum and your new unit.
Jim M
