My self, I'd like something to replace these barn door trailer tow mirrors on my F350.
Someone (probably aerohead) posted a study that claimed 8% of the aero drag on cars is due to side-mounted mirrors. It's probably more for these elephant ears.
The TT mirrors also make the truck a PITA to park in tight spots.
