Jim Ive thought of a swivel bar setup to tow a dead quad with as well,it would keep it from running into the back of my quad..but nothing seems to be versitile enough to really handle everything that comes up..except the HD bumper on my quad,we just ratchet strapped the dead quad to it with some upwards pull and go,just get the front wheels off the ground,with 8-10" of 'leash' so to speak and it just goes..I towed a friend off a mountain in KY-(Evarts,KY-Harlan,KY)-some of the most aggresive territory Ive ever ridden..the quad(Twin Peaks Kawi) held tight and came down off that mountain..we were up so high on the mountain we came down thru the clouds into and thru a rainstorm..what a miserable night..never forget it
