Sealed beams tend to be an enemy of aerodynamics, mostly because American regulations forbid the fitment of any flush cover to headlights. Didn't apply to Brazil, yet this local GMC (technically more related to the C2500 despite the 3500 HD badging) was still alligned to that rule.

Not sure how much of a drag penalty is the spare tire location under this tonneau cover.
