I may at a later time mount a box but for now the plate you use with multiple holes/slots for tie downs would be optimal. I am in the NW Pacific mountain time zone, whens a good time to call and I'll plan accordingly.
hopefully there's no regret, just last night I found a deal on side racks at Ebay. They are the Von-Hepco & Becker model(new) 170 plus shipping sorry just couldn't resist at less than 300. So now I am looking to have your rear rack on soon as well if its available, my V is a 2009. I don't recall the specific difference between the aluminum and steel versions other than you had some photos and you had listed a time or two on ebay.
