Hi margaritaville,
Welcome to the Heartland Owners Forum and family. We have a great bunch of people here with lots of information and all willing to share their knowledge when needed.
Look up by the front of the awning outside and you will see a electric outlet. That switch should control what ever you plug into that outlet. You can open the window in the bedroom to plug something into it.
Enjoy the forum and check out the Heartland Owners Club, lots of good benefits.
