Pressure vacuum tank trucks from J&J Truck Bodies & Trailers are available in capacities of 3,360 to 6,000 gallons. The tank is butt-welded to the shell by Submersion Arc Welding (SUB-ARC) for 100 percent weld penetration. They also have two anti-surge baffles made from the same material as the heads. Tank bodies are outfitted with one-piece aluminum hose trays and polyurea chip guard along the full length of the tank, providing added protection when loading and unloading hoses. A heavy-duty, large tow flap and pin and pipe will pull more than 80,000 pounds. All valves are equipped with heat jackets that operate from the engine’s cooling system. Options include interior tank liners, electric hose reels, toolboxes and onboard scales. 800/777-2671; www.jjbodies.com.
