Hi Scsimonton,
Welcome to the Heartland Owners Forum and hopefully 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 am sure the sofa in the rear will convert to a bed. Don't know if it's air bed or regular mattress,, you might call to make sure. Have you looked at one at your dealer if not, go and check them out in person. That way you will see all the good things.
Enjoy the forum.
