Most vehicles were comprised of either a removable cab/trailer or one-piece base/cab painted in different Specrtralame colors. One cool thing about the series is that the some of the bases could be interchanged. For example, you could simply lift the trailer with its ball joint from this moving van and put it on the fire truck. It was a little trickier with one-piece bases as you'd have to pry the snap-on parts off.
