I live in Louisville. I've only had my Slingshot about 3 weeks and the Baker luggage racks were one of the options I've been looking at. Since you are within driving distance I guess I better double down on my research.
I'm undecided at this time as I'm still researching what direction I want to go with additional luggage options. I was asking your city/state so that I might be able to decide what shipping might be if I decided to buy. Since you are so close I would drive over and pick them up. I haven't seen anything in my research on them as to what the maximum allowed weight for the rack is. Do you know or was anything provided when you purchased them.
Sorry to possibly get your hopes up for a sale. Like I said I've only had mine about 3 weeks and doing tons of research on what is out there. I may end having to build my own setup. thanks for you time.
