Dry Van vs. Flatbed vs. Reefer: Choosing the Right Trailer Type

Start With What Your Freight Actually Needs

Trailer selection generally comes down to three questions: how is the freight packaged, how does it need to be loaded, and does it require a controlled environment during transit? Boxed or palletized goods that just need to be kept dry and secure are a different problem than an oversized piece of equipment that has to be lifted on by crane, and both are different from a product that will spoil if the temperature swings even a few degrees. Working through those questions first, before looking at rates or availability, is what keeps a shipment from being booked on the wrong equipment.

It's also worth remembering that these categories aren't always mutually exclusive in a shipper's overall freight mix. A single business might regularly need dry van capacity for finished goods, flatbed capacity for raw materials or equipment, and reefer capacity for a smaller line of temperature-sensitive products. Understanding the general strengths of each trailer type makes it easier to specify the right one for each shipment rather than defaulting to whatever was used last time.

Dry Van: The Default for Boxed and Palletized Freight

A dry van is an enclosed, box-style trailer, and it's the most common equipment type for general freight. Because it's fully enclosed, it protects cargo from rain, wind, and road debris, and it keeps freight secure from the point it's loaded until it's unloaded at destination. Dry vans are typically loaded and unloaded through rear doors using a dock, forklift, or pallet jack, which makes them a natural fit for boxed goods, palletized products, retail merchandise, and most manufactured or consumer goods that don't require special handling.

Dry van is generally the right default whenever freight is packaged conventionally and doesn't require side or top loading, a controlled temperature, or accommodation for unusual dimensions. Its enclosed design also means less exposure to the elements during transit and at intermediate stops, which matters for freight that's sensitive to moisture or dust even if it doesn't need active temperature control.

Flatbed: Built for Oversized, Awkward, or Crane-Loaded Freight

A flatbed trailer has no walls or roof — just a flat loading deck. That open design is exactly what makes it useful for freight that a dry van can't accommodate. Because there are no side panels or rear doors to load through, freight can be loaded from the side, from above, or lifted directly onto the deck by crane or forklift, which is essential for anything too large, heavy, or oddly shaped to fit through a standard trailer door.

Flatbeds are a common choice for machinery and industrial equipment, building materials like lumber, steel, and pipe, large vehicles, and other oversized or non-palletized items. Because the freight is exposed to the weather during transit, flatbed loads are typically secured with straps, chains, or other tie-downs, and covered with tarps when weather protection is needed. Some oversized flatbed loads may also require permits or escort vehicles depending on their dimensions — a separate consideration from the trailer type itself, but one worth planning for early if your freight is unusually large.

Reefer: For Freight That Requires a Controlled Temperature

A reefer, or refrigerated trailer, is an enclosed trailer equipped with a cooling unit that holds the interior within a set temperature range for the duration of the trip. Unlike a dry van, which only shields freight from the outside environment, a reefer actively maintains conditions inside the trailer regardless of what the weather is doing outside. That makes it the right choice for freight where temperature stability, not just weather protection, is the priority.

Perishable food and beverages, pharmaceuticals and medical supplies, floral products, and other temperature-sensitive goods generally require reefer equipment. Because the requirements for reefer freight vary significantly by product — a load of frozen goods and a load of fresh produce need different handling even though both move in a reefer — shippers with temperature-controlled freight should look at our dedicated refrigerated (reefer) freight guide for a closer look at packaging, monitoring, and booking considerations specific to that equipment.

Comparing the Three at a Glance

The table below summarizes the general fit for each trailer type. These are typical use cases rather than strict rules — some freight can move on more than one trailer type depending on packaging and other specifics, which is part of why it's worth discussing your freight directly when requesting a quote.

Trailer Type	Typical Freight	Key Considerations
Dry Van	Boxed and palletized general freight, retail and consumer goods, most manufactured products	Enclosed protection from weather; loaded through rear doors; the most common default equipment type
Flatbed	Machinery, building materials, oversized or irregularly shaped items, large equipment	Open deck allows side, top, or crane loading; freight is exposed to weather and secured with straps or tarps; may require permits if oversized
Reefer	Perishable food and beverages, pharmaceuticals, floral products, other temperature-sensitive goods	Enclosed with an active cooling unit; requires clear temperature range and monitoring; specifics vary by product

When You're Not Sure Which Equipment Fits

Some freight doesn't fall neatly into one category — a palletized product that's also temperature-sensitive, for example, or an oversized item that could theoretically be broken down to fit a dry van but shouldn't be. In those cases, the packaging, dimensions, and any handling requirements of the specific shipment matter more than a general rule of thumb. Our commercial freight services cover a range of freight types and equipment needs, and the most reliable way to confirm which trailer type and equipment availability fit your shipment is to request a quote and describe the freight directly.
