I am in the middle of sandblasting my Hensley and A frame. This necessitated me taking the AS, just towed by the ball, no WD, with a 2500HD Silverado. It had been decades since I towed anything of any size w/o WD. Try it once and you will understand the reason for WD....and I never approached any speed over 40mph on the move.
The trailer was definitely inclined to be more "in control" of the rig, instead of the other way around.
