I don't recall the "Classic Elite." When I bought mine in 2004 there was the Classic and the Classic Supreme. Anyway I assume that it was the one without the bubble top. And also as I recall, the Ford 350 didn't have the V-10 at GWV. My 2004 on the E-350 was a V-8.
I got 11-12 mpg in town and 13-16 on the highway depending on the winds and topography. I almost never went over 65 mph because it was such a horrible handling thing.
