Before it could cross a puddle or a rock could chip its dump body, this circa-1936 Mack Jr. Model 20-MA was photographed with a freshly installed dump body. The Model SL-11 steel dump body was presumably made by Heil, also the supplier of the rig’s SL-1 hydraulic hoist, but painted and mounted by Mayer Truck Equipment. This truck rode a 139-inch wheelbase and would have had a 209-cid six-cylinder good for 72 hp. According to the doors, this Mack Jr. serviced the taxpayers of Cumberland Township.
