just reporting back and total of of 2300 miles to and from Sedona 3 days and no discomfort. ran pretty much non stop tankful to tankful generally around 350 miles or longer. I was impressed with the mpg at 80+mph.i am sure physical size has a lot to do with it. I am 5'9" and wife is 5'2". we are taking off for Sedona from Montana on Friday and may do it in one shot.
