Not necessarily. False hitch often "looks" true...coupler can appear to be almost all the way down on the ball, it's just not latched. A trailer can go quite a ways before it jolts off the ball, especially if you've got weight distribution and/or sway bars hooked up too.
If WD is hooked up it is impossible for the hitch to come off the ball.
Try this for yourself to see.
Hookup everything. The unlatch the hitch. Now use the tongue jack to try to lift it off the ball.
It can't be done.
You missed the point of my response- I addressed the O.P.'s proposed scenario, wherein I was some towing virgin picking up a trailer at the factory, and they did all the work including hitching up. In that case, assuming the dealer was unprotective of his own interests enough to do the "hitching" to someone else's vehicle, he'd be responsible for any "false hitch" (which I believe is most likely what happened here).
That was obviously not the O.P.'s scenario- he's supposed to be a professional and as such will presumably bear responsibility for any failures of vigilance that may have lead to WHATEVER happened. The details of which we continue ignorant of.
For myself, I permit no one but me to hitch a trailer to my tug. I want to be assured that everything is done as it should be, and all steps taken including jacking to test the integrity of the hookup.
As for W/D being some kind of protectant against decoupling, I call bushwa. The system has plenty to do without having to retain the ball on the coupler to boot. I said that it would likely delay a decoupling, but it certainly can't be depended upon to prevent such an event. There are tremendous forces involved, and W/D add-ons are not designed to take up the work of the coupler as well as their own.
It is
not "impossible" for decoupling to occur in the presence of a W/D system.
