I feel very little sway when truckers go by, pulling out of driveways...
Once fitted to my truck, it's easy to hook up.
I like the solid contruction without chains.
The ball has a 10,000 pound rating.
It takes the stress out of towing.
Payed around $355 U.S.
It's supposed to work with mechanical brakes like boats as well.
I'm not affiliated with Equalizer in any way - just love this product.
