Mike there are allso knock offs of the King hauler and the Areomax made by Amex toys not sure on the spelling. The King knock off is so close it will mount right on a king hauler and even has the holes molded into it for the light unit. I don't know who exactly makes the MACK body I have but I know they are hard to find. Pitbull here on the board has some.
Here are some pics of Pitbulls trucks.
