The Cooling Concepts 53-foot Step Deck Combo trailer earns its “combo” name from the two different materials used in its construction. The 120-inch upper deck is made of steel, while the lower deck is crafted from 1.25-inch aluminum. This design results in a reliable and sturdy flatbed, ready for long-haul transportation. Additionally, it is supported by our Fleet Service Center, offering roadside assistance, and our Back-Office support, which handles DOT and maintenance information tracking.
