Lets talk about sliding bar hitches, are they not designed to come across the narrow part of the the king pin, to hold the king pin in there tight, no fore ,and aft movement to speak of ??
What I am asking is ,if I am thinking right . Wouldn't the high hitch be with the king pin sitting on top of that bar or jaws , thats my understanding of high hitching. So if that is the case here, how much gap would it take for that sliding bar to freely start to close. IMO that would have to be pretty high . If the sliding bar was level with the larger diameter of the king pin sitting up whatever that would be ,would it even let that bar slide over at all, remember its tight in there to allow it to be tight around the smaller portion of the pin.
Maybe someone can explain better how that hitch could of been high hitched ,and then appear to have little or no gap . I don't understand how that bar can come partially across UNLESS it coming across the narrow section of the king pin, then how can anyone call that high hitching .
