Measuring 42 feet in length and weighing 10,000 pounds, the Trail King APBE 1600 is billed as one of the most compact, maneuverable pneumatic bulk trailers on the market. Its external ring design reduces the amount of internal product build-up. It also features a thicker aluminum body shell, which increases the strength and durability of the tank. The unit has mandrel bent piping throughout, which is said to provide unobstructed product flow, reduce friction, and lower unloading temperatures.
