Dry Van vs. Step Deck – FTL Freight Trailer Specs Compared
When you’re booking a full truckload, the trailer type decides almost everything about how the freight moves.
When it comes to FTL freight services, there are two choices that show up: dry van and step deck. At first glance, dry van and step deck might look the same, but dry van and step deck actually solve different problems.
Transport Topics reported that FTR Transportation Intelligence tracked dry van and refrigerated van trailer orders falling year-over-year in 2025, while flatbed and other vocational segments held up comparatively well even as overall production declined. That kind of demand split reflects a deeper operational reality – dry van and step deck trailers serve very different freight profiles, and choosing between them comes down to whether the load needs weather protection or extra vertical clearance for taller cargo.
What a dry van actually gives you
A dry van is the closed box most people picture when they think of a semi in FTL freight services. The common 53-footer gives you roughly 53 feet of floor, a bit under 102 inches of width, and about 110 inches of height inside. You can put 26 standard pallets on it and load 42,000 – 45,000 pounds. Its loading doors are at the rear, its flooring aligns with the docking system, and after closing the doors, it is protected from bad weather as well as theft.
That is why it is used for carrying the bulk of cargo that comes every day, which includes anything packed in boxes or pallets.
How a step deck works differently
A step deck works the opposite way in FTL transport. It is an open trailer with a step in the middle. The front section sits about five feet off the ground. The longer back section drops to around three and a half feet. That drop is the whole point.
On the deck, you can usually stack freight up to ten feet high and still stay under the legal overall height of thirteen feet six inches for FTL loads. The length is 48 or 53 feet total, the width stays 102 inches. The weight capacity is close to a regular flatbed – mid-40,000s. You can load from the side, the top, or drive equipment on with ramps. Tarps cover it when rain is a concern.
Making the call
The choice is rarely complicated once you measure the load. If the freight fits inside a standard box and needs to stay dry, take the dry van. If it is too tall for a normal flatbed deck but does not need a full lowboy, the step deck usually solves it without permits – a decision FTL freight services can help guide based on your specific load requirements.
