"I read about ones that can attach to your kingpin. But would there be clearence on tight turns?"
The newer DRV's have the front cap extending past the kingpin so my "hitch" I fabricated would NOT work on current 16 DRV.
I could make a new hitch but then my toolbox would not open with bikes attached. This custom hitch and Swagman carrier worked well with the 07.5 MS.
