Hi kwright73,
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.
When you go to pick it up do a very good, slow PDI. Make sure they have water and elec hooked up. Test everything and make sure everything is working correctly. If you find anything try to get it fixed before you sign the final acceptance paper work.
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
