I tend to be in awe of just how efficient they are with being built like barns.
In a 53' trailer there's something like 3950 cubic feet of space and a 60,000# payload and with the right truck hauling it they still somehow eek out a handful of miles per gallon at the very minimum.
That's got to be equal to the loads of about 40 to 80 cars... which effectively makes them the equiv of a reasonably loaded car getting 200 to 400 MPG.
BTW, they should all have protective side-fairings for the sake of pedestrians, cyclists and cars... very few in North America do.
