HI Hoot1156,
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 suggest you call Heartland Customer Service, 574-262-8030 or 877-262-8032, have your VIN when you call and they can tell you what they use. If your a member of the Heartland Owners Club you will also get a discount if you order from Heartland Parts.
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
