Yes, a plug for the docking hardware...

I guess there are some folks who have no interest in switching up their bike for different rides. However, I sure do find the 4-Point Docking Hardware handy. I've got a buddy who has a fixed mount for his tour pack and still frequently takes it off for solo rides. Way too much hassle! I can switch between variants in minutes, or less...
[Full disclosure - my bike is a standard and has no electrical connections (lights/audio) on the Advanblack tour pack]
