Two additional thoughts on the keyed-locking pins: 1) in an emergency [eg coach on fire] its going to be hard enough to get the toad unhooked with standard pins--keyed pins will just add to the frenzy; 2) the keyed pins tend to rotate in the hitch as you go down the road, causing some unusual wear on the hitch components--guess lubricant would help but then you attract dust and grit which isnt good for wear either. I like the pins with the spring-loaded fold-over clips.
Realize you were stuck in place but Blue Ox will rework you hitch at FMCAs or Quartzsite for little or no charge.....[guess damaged parts are extra]
