I model SP and its subsidiaries, including PMT truck lines and the A-Line White Freightliner tractor is at the forefront. These are actually Athearn models under a different name. Maybe that stands for the A in A-line. I can't swear to that but that seems to be the case since the models are identical in every way. All painted parts have a realistic dull finish. Printing on the cab doors could be sharper. Wheels could have sharper detail and the tires need to be painted to get rid of the semi-gloss appearance. In addition the wheels need to be enlarged on the back so that the axles will fit into the wheel backs completely. The one piece glazing has a bit of a cloudy appearance. Stirrups are molded but appear to be to scale. There are lights molded on the cab roof and can be dotted with orange paint. As for placement of fuel tanks and battery box there are options. There are no outside rear view mirrors. There are two speed differentials for each rear axle under the chassis but there are no drive lines in evidence. The fifth wheel is unremarkable. All in all an average model with the attention to detail as described. Without it, it is passable but sub-par, making it barely recommendable.
