J&J Truck Bodies & Trailers, a division of Somerset Welding & Steel, was first established in 1958 and began by building steel dump bodies for coal haulers and farmers - the backbone of the local economy at the time. As the economy of the area changed, so did the needs of customers. To answer this need, J&J Truck Bodies & Trailers expanded and diversified its product line, introducing the DynaHauler series. These precision-engineered truck bodies are built to satisfy the demanding requirements of the most rugged and varied applications. By the early 1980s, J&J began manufacturing transfer trailers for solid waste, agricultural, recycling and municipal applications. The company manufactures compaction, live floor, tipper, steel lightweight and push out trailers for commercial and municipal use. Employing 250 people in three facilities totaling more than 260,000 square feet of manufacturing space, J&J is located in Somerset, Pa., approximately 65 miles east of Pittsburgh.
