Those are all beautiful builds, Tim! I've never really been a truck modeler, but the excellent builds like yours and others on this forum are showing me the appeal of this segment of the modeling hobby. There is a lot of opportunity for detailing, and you'll probably never run out of different corporate paint jobs and markings to use on them! Nice work!
BTW, I do have one rig from AMT about 40 years ago called the California Hauler Truck. It's a Peterbilt cab with a sleeper and a box trailer. Maybe it's time for a rebuilding project!
