Semi tractor you say.....
Well these are reproduction cabs, and the dump beds ( I bought 4 from a guy) were rusty and a little bent up and some were missing tail gates so the collectors didn't want them, so no collectable was harmed in the making of these trucks.
Ironically I wish these had just a little more detail in the cabs just a little. I'd like to figure out some 1/16 sized air horns and cab lights, the 1/14 stuff is just to big and it looks like the 1/24 stuff would be way to small.
