Construction equipment, agricultural machinery, industrial components — freight that's too tall for a standard flatbed and not big enough for a lowboy. That's step deck territory. We find the loads, handle the permits, and plan routes before you roll. Average $2.55–$3.20/mile.
The Step Deck Advantage
Know your states' permit thresholds before accepting loads. Carriers who are comfortable with oversized permits and escort coordination access loads that most competitors skip — and those loads pay accordingly.
State-by-state permit paperwork, route clearance verification, and a complete permit packet delivered before the truck departs. No discovering requirements mid-route.
General truck routing software doesn't account for permit load clearances. We map each route against bridge databases and known low-clearance obstacles.
Equipment constantly moves between dealer lots, job sites, and repair facilities. Direct relationships with regional dealers produce loads that never hit public boards.
August through November, combines and large tractors are moving across the Midwest and South. We plan around these seasonal patterns so you're positioned before the surge.
When escort requirements apply, we coordinate pilot car vendors as part of the dispatch. Escort costs are negotiated into the shipper rate before the load books.
Shippers with over-height freight don't have many options. That's a negotiating position. We push rates 20–35% above standard flatbed because the market supports it.

The Complete Guide
A step deck trailer — also called a drop deck — is built in two levels. The upper deck sits at the standard 48–54 inches off the ground. The lower deck drops to roughly 34–40 inches. That 10-to-12-inch difference is the whole business case. Cargo that stands 10 to 10.5 feet tall can clear a 13'6" bridge on the lower deck. The same freight on a standard flatbed would be over legal height limits before it left the shipper's yard.
In practice, that means step deck carriers move freight that standard flatbeds simply cannot legally haul — excavators, forklifts, skid steers, combines, telehandlers, prefabricated wall panels, industrial air handlers. Shippers with this kind of freight have a short carrier list, and that shows up in rates. Step deck currently runs $2.60 to $3.50 per mile on most lanes versus $2.20 to $2.80 for comparable standard flatbed. The complexity premium has held because the pool of experienced step deck operators willing to manage over-height equipment hasn't grown fast enough to close the gap.
Step deck sits between two ends of the flatbed spectrum. Standard flatbeds take the straightforward freight — steel, lumber, building materials under 8.5 feet tall. Full permit loads — large beams, transformers, turbine components — require specialized multi-axle trailers, detailed route surveys, and escorts at every state crossing. Step deck handles the space between: specialized enough to command a rate premium, manageable enough that a single experienced operator can run it every day without a dedicated permit coordinator.
Federal legal limits are 8 feet 6 inches wide, 13 feet 6 inches tall, 48 feet for a single trailer, and 80,000 pounds gross. Any load within those dimensions on a step deck moves without a permit. The moment any measurement crosses those lines, you're in permit territory — and the complexity and cost scale with how far over you go.
Width violations are the most common trigger. Equipment 9 feet wide — 6 inches over the legal limit — needs an over-width permit in every state on the route. Most states issue single-trip permits for loads up to 14 feet wide without a full route survey, but processing time varies. Texas runs most over-width permits through its TxPermit system within hours. California's CalTrans process takes longer. A multi-state load needs a separate permit from each state DOT, which is a meaningful administrative task — and one of the main reasons step deck operators working with dispatch services come out ahead on permit loads versus managing filings themselves.
Route restrictions add the final layer. Standard truck routing software doesn't account for bridge formula weight calculations on specific structures or low clearances that aren't in public databases. Permit loads need a route verified against state DOT bridge databases before the truck moves — not on the road when you encounter a problem. Step deck operators who learn to do this themselves, or work with a dispatcher who handles it, access loads that carriers who skip this step can't run.
Construction equipment dealers and rental yards are the most consistent source of step deck freight. John Deere, Case Construction, Komatsu, Caterpillar, and Volvo CE all operate dealer networks with dozens of locations per state. Equipment moves constantly between dealer lots, job sites, and repair facilities. A John Deere 310L backhoe stands approximately 9 feet 9 inches to the top of the cab — too tall for a standard flatbed, right-sized for a step deck lower deck. The same applies to mid-size excavators in the 30,000- to 50,000-pound class, compact track loaders, and telehandlers. Regional dealer relationships in construction-heavy markets like Texas, Florida, Georgia, and the Carolinas can sustain a step deck operator with enough recurring freight to largely eliminate spot market dependency.
Agricultural machinery drives a clear seasonal pattern from August through November — harvest season across the Midwest and South. Combines, headers, and large tractors move between farms, dealer lots, and storage facilities. AGCO's brands (Fendt, Massey Ferguson, Challenger) run regional dealer networks where equipment relocation is constant. A Challenger MT700 tractor stands over 10 feet to the exhaust stack. Outside harvest, the same dealer networks move planters, sprayers, and tillage equipment — freight that pays step deck rates because of height or width.
The renewable energy sector has added a newer but growing freight category: solar tracker frames, inverter skids, transformer units, nacelle components for smaller wind turbines. Industrial HVAC — rooftop air handlers and chillers being relocated during commercial construction — is another consistent category. Prefabricated building panels and modular units for hotel and apartment construction increasingly ship by step deck because modern prefab dimensions push past standard flatbed height limits.
Step deck rates are genuinely higher than standard flatbed. The profitability calculation requires accounting for costs that don't appear in a dry van or basic flatbed operation. Operators who understand the full economics consistently outperform those who look only at rate per mile when deciding whether to take a load.
Loading time is the most consistently underestimated cost. Loading and securing a piece of construction equipment takes two to four hours versus 30 to 60 minutes for a flatbed lumber load. That time is unpaid. On a 300-mile load at $3.00 per mile, you gross $900. If loading took three hours and driving took five hours, your effective hourly rate across the full 8-hour day is $112.50. Compare that to a flatbed driver who loaded in 45 minutes, drove 350 miles at $2.50 per mile for $875, and finished in 6.5 hours — an effective rate of $134.62 per hour. The higher rate per mile doesn't automatically mean better hourly earnings.
Securement knowledge is a real competitive advantage. Knowing which tie-down points on a specific machine are rated for the load, how to distribute chain tension to avoid damaging hydraulic lines or sheet metal, how to brace a load against hard braking — this takes time and experience to develop. Operators who have it earn higher rates because shippers trust them with freight that a general flatbed carrier couldn't handle correctly.
Loading assistance negotiation is a conversation that needs to happen at booking, not at the shipper door. Most equipment yards and construction sites have forklifts or riggers available to assist with loading. Negotiate for that assistance or negotiate a higher rate to account for loads where you manage it entirely. A $3.20 per mile load that takes four hours to load and three hours to drive produces worse hourly economics than a $2.80 per mile load that loads in 45 minutes and covers 400 miles.
Most dispatch services handle step deck loads when they come up. We built our program around step deck freight specifically, which means we know which brokers consistently have construction equipment loads, which shippers move agricultural machinery through our operating corridors, and what the permit thresholds are in the states where our drivers work most.
Our broker relationships are built around the freight categories that generate high-value step deck loads: construction equipment dealers, agricultural machinery distributors, industrial equipment manufacturers, and renewable energy component shippers. These relationships produce loads at $2.60–$3.50 per mile because we're sourcing from shippers who need step deck capability, not competing on public boards for the same over-height loads that every flatbed carrier is also bidding.
Permit coordination is fully managed — every state in the route, all filings, the complete permit packet and approved route delivered before you depart. Pilot car coordination when escorts are required. Permit costs negotiated into the shipper rate at booking, not discovered after the fact.
Our fee is 5–7% of gross load revenue. No contracts, no monthly minimums, no setup fees. Apply at /dispatch/apply — setup takes under five minutes and we start sourcing step deck freight within 48 hours of approval. If you're running step deck and want consistent access to the high-value freight this equipment is built for, this is where you start.
