Yellow was the predominant colour one day when I spotted this pair.
This Freightliner 122 set back already has a Simard second steering axle added but not connected. These narrow integral mini-sleepers seems to be more common now and are popular with specialized carriers.Note the quad air horns.
A Pete, also with quad air horns, and equipped with a pair of drop axles, and a wide stance front axle was also waiting for work. It was driven from the Pete factory in Texas.
