Anyone ever broke a chain hook-up on WD hitch?

What does that do when you lose half your distribution system? Did you pull the other bar and go on until you could fix it or were you just dead in the water?

Is half the system on just one side better or worse than none at all?

That's what I mildly worried about is if you're running along at highway speed and one side or the other lets go, what impact does it have on the overall rig? Still, at what point do you say enough spare parts. The little hook assembly is cheap and weighs little.
