Actually the metric thing isn't a real big deal but it would be enough to bug me. On the speedo, bigger numbers on the outside of the dial vs inside. The rest of the electronic readouts can be adjusted through flicking a switch. Other things like daytime running lights in Canada, etc.
Some other opitons were power sliding rear window, moonroof, 15k trailer hitch, stability package, and a few other things I forget. The Harley package, though is much more than a loaded f350. The additional items on it are a ton of things. The list I have is a full page of items, too numerous to mention here but things like carbon fibre in places, Harley logo in windshield, wheel hubs, seats, etc., chrome lumber adjustment knobs, chrome tow hooks, special grill, a bunch of things that tricks it out nice.
