After some 50,000kms with a Trigg or treg hitch, whatever one I have, I'm going for a McHitch more versatile and easier to hook up, Treg gives a reliable coupling, better shock absorbtion than a ball any day and great articulation on the worst dip or driveway but a McHitch is just like hooking up a 40footer, easy, peasy.............and gives the same flexibility in situations that a ball couldn't.....you don't need to go off road.
Neither of them will pop off either.
