I don't like the hitches that are being sold for the F3S. As soon as I get home I will getting back to fabricating our version of one. It will not use the lugs for the fender to be attached. I really feel that they are not strong enough to hold over time and will crack and possibly completely fail. They just aren't strong enough. I will give updates on progress. My goal is to have it ready for Spyderquest in September.
