Step deck (drop deck) trailers have two deck levels: a short upper deck near the cab and a longer, lower main deck for the rest of the trailer. That lower deck height means taller freight — like machinery, tall equipment, or manufactured structures — can clear standard bridge and overpass heights without needing an oversize permit.
Typical figures for this equipment type — exact specs vary by carrier and manufacturer.
Tell your dispatcher which configuration you run — it changes which lanes and rates you're matched to.
Fixed two-level deck for most tall-freight lanes.
Deck length adjusts for unusually long freight.
Built-in ramps for drive-on or roll-on equipment.
No long-term contract, no upfront fees — talk to a dispatcher who already knows your equipment.
