With a p.f. of 0.84, you get CdA = 8.85 ft².

I don't like picking on the newcomer, but I would like to hear where our calculations differ.

In any case, it's got aerodynamics somewhere between that of a minivan and a midsized car.
I believe I read in your "CdA list" thread that you multiply by 0.81...

Width = 66.7" = 5.56ft
Height = 65" = 5.42ft
Cd = 0.35

5.56 * 5.42 * .35 * .81 = 8.54

CdA = 8.54 ft^2
