J'J Truck Bodies ' Trailers has introduced a new dual dump body to its line. The unit is designed for road crews who need a safe, effective way to spread salt, sand, and other anti-skid materials. The 10-foot dual dump can dispense materials on either side of the body, allowing for salting ahead of the truck's own rear wheels. Dumping in the forward mode maintains the load between the axles, eliminating potential over-center dumping situations.
