J&J Truck Bodies & Trailers DynaHauler Material Hauler
J&J’s most popular product model, the DynaHauler Material Hauler (MH) dump body, is the workhorse of coal and aggregate hauling. Available in steel and aluminum (pictured), these precision-engineered dump bodies are built to specification and will withstand many years of hard service. The aluminum material hauler is light weight, corrosion resistant and the company’s No. 1 selling commercial dump body. Built to any length, from 13 to 20 ft., its standard features include a dirt-shedding catwalk with inside cleaner plate, a side-mounted hydraulic tank, a ladder and steps, tailgate chains, and tarp rods.
