Hi Donail,
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'm sure since you have had other units you know how things work. But when you go to do your PDI make sure that the Sequoia is hooked up to water and electric. Then check every thing from top to bottom. Make sure everything works and you can work everything. Check out the TV's operation and sound system,, make sure you know how it works. Lots of new stuff, new ways to do it.
Enjoy your new unit and think of joining us at a rally when you can to meet lots of great Heartland Owners and eat lots of good food.\
