Picking the wrong equipment is one of the most common reasons a freight quote changes, or a pickup goes sideways. A load that looked like a van shipment turns out to need a crane. A "small" machine turns out to be too tall for a standard flatbed. A light crate gets quoted on a 48-foot trailer when a hotshot would have done the job.
This guide compares the three main options, plus the step-deck, in plain terms. Want a quick answer? Our Trailer Selector asks five questions and recommends a trailer type.
The comparison at a glance
Figures below are typical ranges. Actual limits depend on the specific truck, trailer, axle configuration and the states on the route.
| Trailer | Deck or box size | Typical max cargo weight | Loading method | Best for | Watch-outs |
|---|---|---|---|---|---|
| Hotshot | Often a 30 to 40 ft gooseneck flatbed pulled by a heavy-duty pickup | Roughly 8,000 to 10,000 lbs with a non-CDL rig (planning range), up to about 16,000 lbs with a CDL rig; confirm the plated payload | Forklift or crane from the side or top; some have ramps | Single machines, crated parts, smaller dedicated or time-sensitive loads | Lower weight capacity and shorter deck; confirm the rig fits your piece |
| Flatbed | Typically 48 or 53 ft long, 8.5 ft wide, deck about 5 ft off the ground | Often around 45,000 to 48,000 lbs | Forklift or crane from the sides, top or ends | Steel, pipe, lumber, building materials, machinery, large crates | Cargo height usually limited to about 8 to 8.5 ft; weather-sensitive freight needs tarps |
| Step-deck | Typically 48 or 53 ft with a lower main deck about 3.5 ft off the ground | Often around 40,000 to 45,000 lbs | Forklift or crane; some loads can drive on with ramps | Taller machinery and equipment that won't fit legally on a flatbed | Shorter usable lower deck; plan where the tallest piece sits |
| Dry van | Typically 53 ft enclosed box, about 8.2 ft wide inside, with a rear door height of roughly 8.5 to 9 ft | Often around 42,000 to 45,000 lbs | Forklift or pallet jack through rear doors at a dock | Palletized, boxed and weather-sensitive goods; retail DC deliveries | Needs a dock (or liftgate/forklift); no side or crane loading |
Six questions that decide it
1. How much does it weigh?
Weight is often the first filter. A piece or load in the roughly 8,000 to 10,000 lb range can be a good non-CDL hotshot candidate, and a CDL hotshot takes more, up to about 16,000 lbs; read 10,000 lbs as the point where a non-CDL rig usually runs out, not as a capacity. Heavier than a hotshot can carry, and you're looking at a flatbed, step-deck or van. Always use the actual weight, including crates and skids, not the product's catalog weight. If you're close to a limit, say so.
2. What are the dimensions?
Measure length, width and height of each piece as it will ship, crated or on its skid. Three numbers decide a lot:
- Length tells you whether it fits a shorter hotshot deck or needs a full-length trailer.
- Width over 8 feet 6 inches is generally oversize and needs permits.
- Height determines flatbed versus step-deck, and whether it fits through van doors.
3. Does it need to be enclosed?
If rain, road spray, dust or sun can damage the freight, you want a dry van or tarps on an open deck. Palletized boxed goods almost always go in a van. Equipment like motors, control panels and switchgear can travel on an open deck when it's properly crated and tarped, but the shipper should say whether the manufacturer requires enclosed transport. See our guide to shipping motors and switchgear.
4. Dock or ground unload?
A dry van works best at a dock with a forklift or pallet jack. An open deck can be loaded and unloaded from the side or top, by forklift or crane, which makes it the usual choice for jobsites, yards and plants without docks. Know what equipment is available at both ends, and its capacity, before you ask for pricing.
5. How urgent is it?
For a smaller load that has to move now, such as a replacement part for a stopped line, a dedicated hotshot is often the practical answer, since the load can travel on its own instead of waiting to fill a larger trailer. For planned freight with a flexible window, a standard flatbed or van is usually more economical per pound.
6. Is it too tall for a flatbed?
A standard flatbed deck sits around 5 feet off the ground, and overall height is limited by each state rather than by a federal rule: FHWA notes there is no federal height limit, and its Size Regulations report puts most state limits between 13 feet 6 inches and 14 feet, so 13 feet 6 inches is the figure most routes are planned around. That leaves roughly 8 to 8.5 feet for cargo. A step-deck's lower deck sits closer to the ground, often allowing cargo up to about 10 feet tall. If your piece is taller than a flatbed allows, a step-deck is usually the next option before getting into specialized heavy-haul trailers. The diagram puts all four trailers on one height scale so the subtraction is easy to see.
Worked example (illustrative)
A crated machine measures 9 ft 0 in tall on its skid, 7 ft wide, 12 ft long and 11,500 lb (all illustrative figures). On a standard flatbed with the deck about 5 ft off the ground, overall height is 5 ft + 9 ft = 14 ft 0 in, above the 13 ft 6 in most states allow without a permit. That turns a routine move into an over-height permit load: a surveyed route that avoids low bridges and wires, possibly an escort, and extra lead time and cost. On a step-deck with its lower deck about 3 ft 6 in off the ground, the same piece rides at 3 ft 6 in + 9 ft = 12 ft 6 in, under the limit with a foot to spare, and it still loads from the side by forklift or crane. At 7 ft wide it is inside the 102-inch (8 ft 6 in) federal width standard, so width is routine too. At 11,500 lb it is beyond what many non-CDL hotshot combinations net, so a step-deck behind a tractor is the practical call. Measure the skid and any blocking before you send dimensions: two inches of blocking makes it 12 ft 8 in, still fine on the step-deck, but the same two inches would have mattered on a trailer with less margin.
Common mismatches to avoid
- Van-loaded freight with no dock at delivery. If the receiver only has a forklift in the yard, a van can't be side-unloaded. Either an open deck or a liftgate arrangement is needed, and that has to be known at quote time.
- Catalog weight instead of shipping weight. Crates, skids and packaging add up. A piece that "weighs 9,000 lbs" can ship heavier, which may rule out a smaller rig.
- Height measured without the skid. A few inches of skid or blocking can push a piece past what a standard flatbed allows.
- Weather-sensitive freight with no tarp request. Open-deck tarping takes planning and is often priced separately. Ask for it up front.
- Assuming hotshot means faster. A dedicated hotshot can move a small load right away, but transit still depends on miles and legal driving hours.
Quick rules of thumb
- Boxed, palletized, dock to dock: dry van.
- Long, heavy, crane- or side-loaded: flatbed.
- Tall equipment: step-deck.
- Lighter, smaller, time-sensitive: hotshot.
Where each applies here: Hotshot and flatbed freight nationwide (lower 48). Dry van truckload across North Carolina, South Carolina, Georgia, Virginia, Florida, Alabama and Tennessee. For dry van, that means a truckload that picks up and delivers within those seven states (NC, SC, GA, VA, FL, AL and TN); a van load that leaves them is outside it, while hotshot and flatbed cover the lower 48.
