From FordTruckWorld.com:
Is this what the 2004 model Ford F-150 will look like? This detailed illustration of the 2004 model was sent to us by an anonymous source, indicating that they are being distributed at Ford production plants where the truck may be built. They are clearly done by a concept artist who has seen the '04 models. We can only speculate that they were done at Ford's design center. TEN contacted a Ford spokesperson who did not want to comment.
These illustrations show in great detail, what the F-150 may look like. They match much of what we have already seen in camouflaged spy photos. If the illustrations are correct, the bold new lines of the 2004 resemble the Tonka Truck concept and has more F-250-like body style, while maintaining the traditional F-150 front fascia. The bulged hood and taller doors are also a nice touch while we can only speculate that the wheel and tire package seems to be in the 17-inch diameter range.
