I now have three very different cars to tow, so I'm wonder about getting a scale to figure out where to place the cars on the trailer (with a weight distribution system, the swaying is minimal, but possibly it could be better). I stumbled across this option. It's a ball mount with a built-in scale. It can be used for towing up to 10,000 lbs with a 2" receiver. Has anyone tried using one?
