This Erie Builders Concrete tractor-trailer mixer rig by John Redding was built from an Athearn Mack B-61 concrete mixer model with the mixer removed to make this truck tractor. The mixer trailer was built using a Herpa mixer barrel mounted on an Athearn 23' container chassis with a powerplant and details installed. The Mack has an added spare tire behind the cab along with a shovel and other necessary details.
