Ford states in their literature:
Frontal area is the total area in
square feet that a
moving vehicle and
trailer exposes to air
resistance. The chart
shows the maximum
trailer frontal area that
must be considered
for a vehicle/trailer
combination. Exceeding
these limitations may
significantly reduce the
performance of your
towing vehicle.
Yep, that's where I read it! And it makes sense. why would you subtract frontal area from an area that's already being used by the TV? I put an air deflector on the roof of the X and it made a huge difference. gained .5 mpg and I noticed that the throttle opening is 15% less with the deflector than without. frontal area makes a difference, but if you change it slightly it helps!
OK, you subtract the frontal area of the truck to get the trailer's frontal area. THEN you have to add the frontal area of the truck to the trailer's frontal area ("Frontal area is the total area in square feet that a moving vehicle and trailer exposes to air resistance") to get the total frontal area. Seems easier to me to just use the trailer's frontal area. You get the same number.
