Measure the tall piece twice
Once against the ceiling figure, once against the opening. A crate that clears 111 inches inside can still stop dead at the threshold, and a driver will not force it.
Trailer types
Dry van freight, from the loading end
A dry van is the plain enclosed trailer that hauls most of what moves by truck in the United States. Booking one is easy. The part that goes wrong is everything the rate quietly takes for granted about your building, your pallets and the shape of what you are sending. Builder specifications and federal limits below were read on 2026-07-29 and are linked where they came from.

A box on wheels, with rules
No prices appear on this page. Trailer builders do not publish freight rates, and a truckload lane is priced by a person against the day it moves.
The trailer as its builder describes it
Numbers first, because most disagreements about whether a load fits are settled by four of them. These come from Utility Trailer's composite dry van specification page rather than from a broker's summary.
| Specification | Published figure | What it means on your dock |
|---|---|---|
| Overall length | 53 ft 0 in | The outside of the box, so the usable deck is a little shorter once the front wall and rear frame are subtracted |
| Inside width at wearband | 100 in or 101 in | Two standard pallets sit side by side with inches to spare, and nothing wider than that goes in at all |
| Inside height | 110 1/2 in front, 111 in rear | The ceiling clearance for a second tier of freight, measured well past the doors |
| Overall width | 102 3/8 in | Built right up against the 102-inch highway envelope, which is why the box never gets wider |
| Overall height | 13 ft 6 in on a 46 1/2 in fifth wheel | The figure that decides low bridges and canopies on the route, not inside your building |
| Payload capacity | 55,000 lb | What the equipment is rated to carry before highway law is even consulted |
| Gross vehicle weight rating | 65,000 lb | Trailer plus cargo, with the tractor still to be added on top |
| Floor | 1 3/8 in laminated hardwood, 20,000 lb front axle fork truck rating | A loaded forklift may drive inside, which is the whole premise of dock loading |
Every trailer in a fleet is not this trailer. Equipment from a different builder or an older build year lands within an inch or two of these figures in each direction, which is fine for pallets and not fine for a crate planned to the last half inch. If your load is that close, ask the carrier for the numbers on the unit they are dispatching.
The door is smaller than the room
Here is the specification you will not find on the builder's page: the rear door opening. Utility publishes the inside of the box and stops there. The opening is always the tighter number, because the rear frame, the hinges and the door hardware take back part of the width and part of the height.
Ask before the truck rolls
Carriers can read the door opening off the trailer they assign. That one question, asked at booking, prevents the most expensive kind of failed pickup.
Roll-up doors cost you inches
Swing doors open flat against the sides. A roll-up door stores its curtain in the roof and takes clearance out of the top of the opening, so the same freight can fit one trailer and not the next.
What a dock-to-dock rate assumes about you
A bare truckload rate covers a driver, a tractor, a trailer and the miles between two doors. Everything else on this list is assumed to already exist at your end, and each item that does not is an accessorial with its own price.
| The rate assumes | If you do not have it |
|---|---|
| A dock the trailer floor can meet, or a forklift that can reach it | The pickup needs a liftgate, and the freight has to be small enough to stand on one |
| Your own people and equipment loading the trailer | Driver-assist or a lumper is arranged and billed separately |
| Freight already on pallets, stretch-wrapped and stable | Loose cartons take far longer to load and travel worse, and damage claims follow the loose ones |
| Someone on site through the whole loading window | Waiting time past the free hours turns into detention on the invoice |
| A yard a 53-foot trailer can actually turn in | The lane may need a shorter trailer, which changes both the capacity and the price |
| Delivery stopping at the receiving door | Carrying goods past that door is inside delivery and is quoted on its own |
None of these are penalties. They are labour and equipment that somebody has to supply, and a rate that pretends otherwise is a rate that gets revised after the fact. Say what your site has when you ask for the quote and the number you are given is the number you pay.
Weight is capped twice, and the lower cap wins
Shippers new to truckload freight tend to plan against the trailer rating and get surprised at the scale. The equipment rating is a property of the trailer. The legal ceiling is a property of the road, and it counts the tractor too.
| Limit | Federal figure |
|---|---|
| Gross vehicle weight | 80,000 pounds |
| Single axle | 20,000 pounds |
| Tandem axle | 34,000 pounds |
| Vehicle width on the National Network | 102 inches, which no state may set higher or lower |
Subtract a tractor and an empty trailer from that 80,000 pounds and the cargo allowance left is well under the equipment rating quoted above. Axle limits bite before the gross limit does: freight bunched over the nose or piled at the doors can put one tandem over 34,000 pounds while the total is still legal, which is why loaders spread weight down the deck instead of building a tower at one end.
When the answer is not a dry van
Flatbed
Loads that arrive by crane or side-loader, structural steel, pipe, tracked equipment, anything over the 102-inch envelope or taller than the ceiling. A flatbed has no door to fit through, and in exchange you supply tarps, straps and a securement plan.
Refrigerated
Produce, dairy, pharmaceuticals, coatings and adhesives with a storage range, chocolate in August. Ask for a reefer whenever the goods have a temperature spec, and hand the carrier the setpoint in writing rather than the word cold.
Still a dry van, smaller
A 28-foot pup or a straight truck exists for tight yards and light loads. Capacity drops with the length, so it is a choice about access rather than a cheaper version of the same trailer.
A dry van is not heated, not cooled and not sealed against condensation. Steel parked overnight in a January yard arrives at the temperature of that yard, and metal that goes in warm can sweat inside the box. Anything sensitive to that belongs in temperature-controlled equipment even if it would physically fit here.

Common questions
What are the inside dimensions of a 53-foot dry van?
Utility Trailer publishes 53 ft 0 in overall length, 100 in or 101 in of inside width at the wearband, and inside height of 110 1/2 in at the front and 111 in at the rear. Older equipment in the same fleet can be an inch or two tighter, so a load planned to the last inch needs the specific trailer confirmed.
Will my freight fit through the rear door?
Measure against the door opening, not the inside height. Builders publish the interior of the box but not the rear opening, and the frame and hardware take some of it back, so the tallest piece you can roll in is shorter than the ceiling suggests.
Do I need a loading dock to ship on a dry van?
A plain dock-to-dock rate assumes a dock or a forklift at both ends. Without one, the pickup or the delivery needs a liftgate, and that is priced as a separate accessorial rather than folded into the linehaul.
How much weight can a dry van legally carry?
Two ceilings apply and the lower one wins. The trailer builder rates the equipment at 55,000 lb of payload, while the Federal Highway Administration caps the whole vehicle at 80,000 lb gross on the Interstate System, and the tractor and trailer eat a large share of that before your freight is loaded.
When should I ask for a flatbed or a reefer instead?
Flatbed when the load cannot go through a door at all: crane-set machinery, long steel, anything wider than the box or taller than the ceiling. Reefer when the cargo has a temperature range, because a dry van is an unheated steel and composite box that sits at whatever the weather is doing.
