I saw this cushioned shank/drawbar unit during one of my many searches for equipment/gear...
inside are polyurethane bumpers/cushions to help reduce vibration.
I believe it's made by the Convert-A-Ball company and re-branded/labeled by various retailers to sell under their names (in this case etrailer.com).
Seems like it would help and I can't see any downside yet. It goes for $89.95 at etrailer.com and I am considering it for when I go pick up my trailer this Spring. My trailer came with a 'standard' WDH system (chains and lift bars - it's NOT a combo WDH/anti-sway unit, though) so there is already a draw bar but this would seem to be a beneficial upgrade.
My new-to-me trailer is a 2000
Burro 17' and my tow vehicle will be my 2005 Honda Odyssey Van (3500# max tow rating 'when properly equipped').
Any opinions from those who do tow with WDH?
EDIT: thought I should mention I did search prior and there was a Legacy Post on this topic of cushioned ball drawbars/shanks/mounts...
