I'm in the market for a trailhawk and trying to decide what I want to do also
It may be a waste of money, or it may be you have not hit the exact magic conditions to set off the death wobble. I have read accounts like yours online before, where people think they did not need it as they had not experienced the death wobble in thousands of miles of towing, then they hit a dip in the road just wrong and set off a death wobble event with their TOAD.FCA likes $$$ I have it installed and never turn it on anymore Total waste of $$$.
