Towing without mounting the anti-sway spring arms (bars)

As the OP can see not all WD hitched are the same. The sway control on our Blue Ox is built into the design.

As to the TT socket jumping off the ball, the latch and cross pin is what is supposed to prevent that.

Since the WD hitch produces an upward force to redistribute the tongue weight, it would seem to increase the possibility of an improperly locked socket jumping of the ball. Especially if the ball is the wrong size.

With my TT and TV combination I much prefer the ride of the WD Hitch.
