Old fashioned fuel tankers from the 50's or so... when they had good looking designs

The fairing from the cab that goes to the back of the rear tires is good for aerodynamics, and good for a couple more miles per gallon, but really makes a semi look good

This photographer was taken with this tanker... why else would he take photos of the front and back?

Looks like a Crosely
