Hi Lamont,
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.
The bolts your using,,, are they a grade 8 and correct size? You need to make sure your using the strongest bolt and it is correct size, 5/16", I think. Some other members will jump in with more info for you soon.
Be sure and join our
Heartland Owners Club, it’s free now. Then join us at a rally when you can and meet lots of the great folks here and make friends for a lifetime.
Enjoy the forum.
