I picked up my Harley Davidson model for $55k Canadian last year brand new, and I bet a fully loaded 2011 King Ranch would set me back about $75-80k. The Harley model won't be out until 2012 when they prove them selves to be worthy enough for Harley to badge them.
though true, and it is nice to have it all factory installed, all of that you can get from aftermarket companies. i am not worried about trailer sway because my trailer stays pretty strait as it is but the fuel economy was not impressive, on the 6.7 truck that i drove i was getting 10.2 and on the 6.4 i was getting 8.6, 2 miles per gallon is not a big deal to me.
