Hi justme,
Welcome to the Heartland Owners Forum and hopefully to the family. We have a great bunch of people here with lots of information and all willing to share their knowledge if needed.
I don't think any of the Heartland units are equipped with surge suppression, but your dealer should call and check for sure for you. There are some things that the factory will add that are not on the published option list.
Enjoy the forum.
