Have been using our setup since day one and no major issues. The wedge has moved slightly back twice now which will cause a bump to the truck when going into corners. It is easily seen in the rearview mirror as the kingpin to hitch connection appears loose and moves side to side when turning. Takes just a few minutes to loosen and readjust the wedge and tighten back down. The bump it gives does make an uncomfortable feeling and could possibly make an issue on wet pavement if your tires are not in good shape.
