I wouldn't really call that a limit but a consideration. Still doesn't mean Ford won't be jerks when it comes to warranty. How do they explain all the pictures in their ads and on the webpages of Ford trucks towing obviously over 60 sqft frontal trailers?

It looks like the SAE has been conducting tow tests up the Davis Dam grade,or equivalent,since 2008.The trucks must maintain 40-mph,so even if aero was a criteria,it's impact would pale in contrast to that of climbing.It's got to handle the desert summer heat,with full AC blasting away.
