Hi Brandon,
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.
Most folks have a welder do the job or the build something to bolt on them selves. I would suggest you call Heartland because you will be modifying the frame and it will probably void your frame warranty.
Check out the Heartland Owners Club and join us at a Heartland rally.
Enjoy the forum.
