Engine temps.

[408F150]

Anti-Sway has saved me many, many time. With how tall toy haulers are (I think mine is 11' 6"?), wind and semi truck gusts will whip you like crazy. It also saved me one time when one of my 4 ratcheting straps I had my quads tied down with snapped. I had 2 400# quads sliding around the trailer and assumed it was the wind. I could feel the anti-sway fighting it, I don't even want to know how squirrelly it would have been without it.
