Types of Dry Van Trailers and the Freight Each One Gets

Every dry van is an enclosed, non-refrigerated box, but the details change what freight you can book. Wall construction decides how wide the inside is, vents and food grade status decide which food shippers will load you, and axle setups decide how heavy you can go. Here are the dry van trailer types you'll see on load boards and in rate confirmations, and what each one is good for.

Types of dry van trailers at a glance

The labeled anatomy in what is a dry van shows where each of these features sits on the trailer.

Plate trailer vs sheet-and-post dry van

This is the comparison that matters most for day-to-day booking, and it comes down to the wall.

Sheet-and-post

The traditional build: thin aluminum or steel sheets riveted to vertical posts, with a liner inside. Current sheet-and-post vans from manufacturers like Strick list interior widths of about 100 to 101 inches, but many older vans on the road are narrower. Damage is easy to fix: replace a sheet or a post.

Plate (composite)

Plate vans use composite panels, a plastic or foam core between steel skins, as the wall itself. Wabash sells these as DuraPlate. The thin wall leaves about 101 inches of inside width on current builds (Wabash lists 101 in; Hyundai Translead lists 101.5 in on its composite van), and the smooth inside doesn't snag cartons. Shippers that load two pallets side by side, or wide cartons, often ask for plate vans by name.

Which should you run? If your lanes are retail and grocery distribution, a plate van opens more loads. If you're buying used on a budget and haul general freight, a well-kept sheet-and-post van works fine; just know your exact inside width before you promise a shipper anything. See the full measurements in 53 ft dry van dimensions.

Vented and food grade vans

Vented dry van

A vented van has openings at the front and rear (sometimes closable) so air can move through the load. It's built for produce that needs airflow to stay sound, like potatoes and onions; USDA research on bagged potatoes found that channels for air through the load helped carry off excess moisture. A vented van is not temperature controlled. Freight that must stay cold goes in a reefer.

Food grade dry van

Food grade isn't a separate model; it's a condition. The van has to be clean, dry, free of odors and pests, and in good repair. FDA's sanitary transportation rule requires vehicles used for food to be suitable and adequately cleanable (21 CFR 1.906). In practice, food shippers will ask what you hauled last, inspect the floor and walls, and turn away a van that carried chemicals or smells of the last load.

If you want food freight, keep a wash-out record, avoid hauling anything that taints the trailer, and sweep and inspect before every food pickup.

Dry van with liftgate

A liftgate is a powered platform at the rear that lowers freight to the ground. Rail-type gates fold up behind the doors; tuck-under gates fold beneath the trailer. A dry van with a liftgate can deliver to small stores, offices and job sites with no loading dock. The gate adds weight and maintenance, and most long-haul freight doesn't need it, so liftgate vans mostly work local and regional lanes. A dry van without a liftgate is the norm for dock-to-dock freight.

Spread axle and multi-axle dry vans

Federal rules treat two axles as a "tandem" when their centers are more than 40 inches and not more than 96 inches apart, and the federal tandem limit on the Interstate System is 34,000 lb (23 CFR 658.5). A spread axle van sets its axles further apart than that, so they aren't counted as a tandem. Depending on the bridge formula and each state's rules, that can allow more weight on the trailer axles. The catch: spread axles scrub tires in tight turns, and states don't all treat them the same, so check the rules on your lanes.

Tri-axle and quad-axle dry vans add axles for heavy freight. How much a quad axle dry van can haul depends on the state's weight laws and permits, not on the trailer alone; these setups are more common in states that allow heavier gross weights on their own roads. The max weight for a 53 ft dry van guide covers the federal limits and the cargo-weight math.

Other variants you'll see posted

• Drop frame and high cube. A lowered floor or taller box for light, bulky freight that fills the trailer before it gets heavy.
• Insulated or heated vans. Insulated walls (Wabash offers a semi-insulated package) and sometimes a heater to keep freight from freezing in winter. Still not a reefer.
• Roll-up vs swing doors. Swing doors give the full opening; roll-up doors are faster at frequent stops but store overhead and can take some height.
• Air ride suspension. Smoother ride for fragile freight; some shippers require it.

Securing freight inside a van

A closed van doesn't excuse you from cargo securement. Federal rules apply to semitrailers, vans included (49 CFR 393.100), and cargo must be "firmly immobilized or secured" within the vehicle (49 CFR 393.106). In a dry van that usually means:

• Load bars (also called shoring bars) wedged wall to wall behind the last row or between partial loads.
• Straps hooked into logistics track or E-track along the walls.
• Logistics posts on sheet-and-post vans, or flush-mount logistics on plate vans, as anchor points.
• Loading tight, nose to door and wall to wall, with dunnage or airbags filling gaps.

Most shippers load and seal the trailer, but you're responsible for what happens on the road. Carry at least two load bars and a few straps, and check partial loads before you pull out.

Which type should you run?

Run what your lanes need. If you're booking mostly retail and grocery distribution freight, a plate van with logistics track covers most loads. If you want produce, add vented capability. If you're doing local delivery, a liftgate earns its keep. When you know your trailer's exact specs, our dispatchers can match dry van loads to it, and our dry van dispatch service tells brokers your specs up front. Run any load through the dry van load profit calculator before you accept it, and see how a van compares with open-deck work in dry van vs flatbed.

Questions owners ask

What is a plated trailer dry van?

A plated trailer (also called a plate trailer or plated dry van) has smooth sidewalls made of composite panels instead of aluminum sheets riveted to posts. The thin walls give you more inside width, usually about 101 in, and the smooth inside resists snags and damage from forklifts. It has nothing to do with license plates.

What's the difference between a vented van and a dry van?

A vented van is a dry van with vents at the front and rear so air can move through the load. It's used for produce like potatoes and onions that need airflow but not refrigeration. It isn't temperature controlled, so freight that must stay cold still needs a reefer.

Can a dry van have a liftgate?

Yes. A dry van with a liftgate has a powered platform at the rear for loading and unloading where there's no dock, like small stores and construction sites. The liftgate adds weight and some loads won't need it, so liftgate vans usually work in local and regional delivery.

What does food grade dry van mean?

A van that's clean, dry, odor-free and in good repair, often with a record of what it hauled before, so it's fit for food. FDA's sanitary transportation rule (21 CFR Part 1, Subpart O) requires vehicles used for food to be suitable and adequately cleanable. Many food shippers won't load a van that last hauled chemicals.

Do I need straps or load bars in a dry van?

Often, yes. Federal cargo securement rules apply to semitrailers, vans included (49 CFR 393.100), and require cargo to be firmly immobilized or secured (49 CFR 393.106). In a van that usually means load bars, straps on logistics track, or freight loaded tight from wall to wall and nose to door.
