This posting is for a Dry Van Trailer only. IT DOES NOT INCLUDE THE TRUCKS on the photos, the trucks are there only to illustrate how the trailer would look with its respective truck.
The trailer model is made entirely of plastic with chrome finish. The wheels are made of rubber and roll very smoothly (just as the truck wheels). The doors at the end of the trailer can open. The trailer measures about 15 inches long by 3.25 inches wide by 5.75 inches high.
The trailer connects to a 1/32 truck by a metal pin which is about 1.75 inches from the front of the trailer. It seems that so as long as your truck model is at a 1/32 scale and has the locking/attaching mechanism that the trailer will be able to be hooked to it. The front supports of the trailer need/can to be folded if attached to a truck.
When attached to a truck the whole assembly should measure about 21 inches long, depending on the length of the truck.
The trailer comes in an individual window box which measures 18 inches by 4 inches by 7 inches.
Note that these trailers, like the trucks, are not really toys. They would not survive being played with regularly. Moreover, it seems that the chrome finish can scratch easily.
