No experience with it but here's a demonstration of it in action. It looks like it's based on the same concept as the US made Equalizer 4 Point hitch but with pads on the frame brackets. The pads look to be about $80 when the time comes. A lot of Reese products are now made in China. Don't know if this one is or not.
