Remember the song "Convoy?" This refer semi reminds me of that song. "10-4 good buddy, we got us a convoy!" I build it with maple. It includes details down to the refer unit, exhaust pipes and spare tire. It measures 39 inches long, approximately 7 inches high and 6 inches wide. This truck is a great piece for any trucker with good memories of his or her time on the road or would also make a great toy for kids four and above.The tractor can separate from the trailer. A great gift!.
