I tried a cheap gopro knockoff (<$25) camera on the tow bar and it worked surprising well. I used the bicycle lock down to attach it near the ring. I haven't seen anyone mention mounting a camera on the tow bar so I don't know if this is copacetic. The plastic mount probably is not a good idea but if this is allowed then I would buy a more rigid bike mount. Ideally I want the camera mounted looking at the rear tires (improve my turning on the slaloms) but starting my turns better also works.
