Hi bobw,
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.
Yes, the wait will be demanding...but,, you can start thinking of things to change, make it your own. Give the wife the credit card,, she will think of lots of things to add also.
When you go for PDI, do a very complete check over.. make sure you can operate everything and everything operates,, from water faucets to draining the tanks,, tv to all the jacks.
Enjoy the forum and your new Bighorn. The Heartland Family is here if you need help with anything.
