So, I can get a used QuickLok intended for a D30 (supposedly made by Genuine Gear?), for like $75. I have found very little info about this thing, but I reckon it's an automatic, gear-driven, lunchbox locker? Anyone have any experience with this unit? I am especially interested in knowing about handling characteristics, “feeling”, and operation on pavement! How would it work in front of a vehicle that mainly sees daily driving? Thoughts?
