Flatbed Stretch
When your load is simply too long for a standard 53′ flatbed, the stretch flatbed extends the deck to eliminate unsafe overhang. The trailer slides out in sections, providing full structural support for long beams, pipe sections, wind turbine components, and bridge materials.

Stepdeck
The step deck features an upper deck (approx. 11′) and a longer lower deck (37’–43′) that sits closer to the ground, allowing taller cargo to be transported legally without over-height permits. The go-to solution for equipment too tall for a flatbed.

Triaxle Stepdeck
The step deck tri-axle trailer is a standard step deck outfitted with a third axle to distribute weight across more contact points. This configuration allows significantly heavier loads to be transported legally. It serves as an economical middle ground between a standard step deck and an RGN for heavy equipment that does not require a full RGN configuration.

RGN
The RGN trailer features a detachable front gooseneck section that hydraulically lowers to ground level, creating a built-in drive-on loading ramp. Self-propelled equipment loads directly onto the trailer without a crane. Multiple axle configurations allow for extreme weight capacities, making the RGN the top choice for the heaviest and most oversized machinery.

Double Drop
The double drop trailer features two drops in deck height, creating an ultra-low center well that sits just 18 to 24 inches off the ground. This design maximizes legal cargo height clearance without requiring height permits. Unlike the RGN, the gooseneck is typically fixed and loading is completed from the rear using ramps or a crane.

Conestoga Flatbed
Conestoga flatbed trailers combine the versatility of an open deck with the protection of a covered trailer. The sliding tarp system allows for quick side, rear, or top loading while shielding freight from weather and road debris throughout transit.
This trailer is ideal for machinery, crated equipment, and high-value materials that require easy loading access without sacrificing freight protection.

Conestoga Stepdeck
The Conestoga Step Deck features two loading levels: a shorter upper deck and a longer lower deck. This design makes it the go-to solution for taller freight that exceeds the height limits of a standard flatbed trailer. The retractable curtain system eliminates the need for manual tarping while keeping cargo fully protected throughout transit.
This trailer is a natural fit for CNC machinery, robotics, construction equipment, and other tall loads that ship without requiring an oversized height permit.

Conestoga Double Drop
The Conestoga Double Drop trailer, sometimes called a Double Drop Curtainside, is built for the tallest and heaviest cargo that cannot ride on a standard flatbed or step deck. Its unique well section drops below the axles, allowing legal transport of cargo up to 11 feet 6 inches tall without requiring special height permits.
The front and rear decks add versatility by accommodating smaller secondary loads alongside the primary freight. This trailer type is ideal for oversized construction equipment, large industrial machinery, and agricultural equipment that demands extra vertical clearance.

Dry Van
The dry van trailer is the most common trailer on American roads. It is a fully enclosed, weatherproof box loaded from the rear via dock or liftgate. Dry van trailers do not include temperature control and are designed for general freight that requires protection from the elements and theft without the need for refrigeration.

Reefer
The reefer trailer is an insulated dry van equipped with a diesel-powered refrigeration unit mounted on the front wall. It maintains temperature ranges from negative 20 degrees Fahrenheit up to 70 degrees Fahrenheit, covering frozen, chilled, and temperature-sensitive freight. Interior dimensions are slightly reduced due to insulation and the refrigeration unit.

A box truck is a self-contained enclosed truck with the cab and cargo box mounted on the same chassis without a separate trailer. It is dock-height capable, available with a liftgate, and highly maneuverable for urban and residential deliveries. Box trucks are ideal for locations that a semi-truck cannot access.
