At highway speeds, the trailer is going to add more wind resistance and be more susceptible to cross winds. This is probably what is causing the sensation that the trailer is holding the truck back and the swaying you are experiencing.

The weight distribution spring bars on your current set up may not be rated high enough for the trailer. You need a system that has a tongue weight capacity range that encompasses 10 to 15 percent of the gross trailer weight when it is loaded and ready to tow. At 8,500 pounds, you would need a system rated high enough for an 850 to 1,275 pound tongue weight.

I recommend a system rated for 800 to 1,500 pounds tongue weight like the Strait-Line Weight Distribution w Sway Control, # RP66130. The weight distribution alone can help a little with sway, but the built-in dual-cam sway control that comes with this system is the best sway control system available. It is a pro-active system that stops sway before it starts.

You would just need an adjustable shank, # RP54970, and a properly sized ball like # 63840. I have included links to the installation details for you to view.

If the truck is sagging in the back, you may be interested in suspension enhancement like # SSR-302-47.
