Hi Gary,
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.
I have a small crankup on my 3055,,,but it is not as heavy as what your thinking of installing. They do have 2 cables in the ceiling for satellite dish installation. I would suggest you have your VIN and call Heartland Customer Service and ask their opinion. 574-262-8030, or 877-262-8032. Let us know what you do.
Enjoy the forum.
