Live Bottom Dump Trailer


The Advantage Series Over-The-Fifth-Wheel Live Bottom (OLB) incorporates lightweight, smooth aluminum sheeting and a re-engineered frame into a new lower, lighter, more aerodynamic and fuel-efficient design. And, by lowering the overall height of the trailer and extending the hopper two feet forward, we’ve improved the load distribution and lowered the payload center of gravity for more load-handling stability. Other features include 36″ belt width patented floor system, and self-lubricating chain oiler system.

The Trail King Advantage Series OLB… destined to be the best live bottom you’ll ever own.
