Hey Ron, welcome back! Hope that steering stabilizer item # RM47MR is working out for you!

Adding or upgrading front and rear sway bars is definitely going to be the way to go. These will take out that top heavy swaying feeling and give you a more stable and comfortable ride. This kits come with all hardware necessary to complete the installation. I've listed the parts you'll need below:

Front Anti-Sway Bar - Roadmaster Front Anti-Sway Bar - 1-3/8" Diameter item # RM-1139-189

Rear Anti-Sway Bar - Roadmaster Rear Anti-Sway Bar - 1-1/2" Diameter item # RM-1139-147

Does your 2017 Forest River Sunseeker have factory sway bars? If it does you'll want to check the diameter of the factory bars to see if these are thicker. The thicker the anti-sway bar is the better it'll perform.

You can add this information and any other questions you have where it says Reply to Jerred H and I'll be happy to answer them.

I've linked a couple of installation videos below along with a couple of pictures so you can see how to get the anti-sway bars setup and what they'll look like once installed.

@Ron The rear anti-sway bar item # RM-1139-147 does require drilling. New holes have to be drilled in the frame to mount the Roadmaster end links.
