Hi Seattle,
Welcome to the Heartland Owners Forum and hopefully the family. We have a great bunch of people here with lots of information and all willing to share their knowledge if needed.
I think we will need more info about your truck,,, 1/2,,, 3/4,,, 1ton... engine???,,, tran,,,You can probably tow a trailer with anything... but can you control or stop it??? Your truck came with a label on the door I'm sure... it would give you what weights you should be able to tow or gross weight capacity and towing capacity. Give us a little more information and I'm sure the others will chime in.
Enjoy the forum.
