Hi wanderer,
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.
I don't use one,,, did try one and sold it to someone else. I don't think they help that much. What does help is the JT Strongarms or something similar. There are a couple more types and some even make their own.
I'm sure you will get some more suggestions also.
Enjoy the forum and attend a rally when you can. You will meet lots of great folks and eat some great food. Infact there is a rally next weekend in Tenn.
