How Much Does a Dump Trailer Weigh? A Complete Guide
If you’re thinking about buying, hauling, or towing a dump trailer, one of the first questions to ask is:
How much does a dump trailer weigh?
Whether you’re hauling gravel, debris, or equipment, the trailer’s weight plays a major role in your towing capacity, registration class, fuel use, and safety compliance.
Let’s break it down clearly by size, type, and capacity so you can make the right decision for your needs.
How Much Does a Dump Trailer Weigh?
The average empty (unloaded) weight of a dump trailer ranges from 1,200 to 6,000 pounds, depending on its size, material, axle setup, and manufacturer.
Here’s a quick look at common dump trailer weights:
| Dump Trailer Size | Empty Weight (Approx.) | Payload Capacity (GVWR – Empty Weight) |
|---|---|---|
| 5×8 Single Axle | 1,200–1,800 lbs | ~2,000–3,000 lbs |
| 6×10 Tandem Axle | 2,000–3,000 lbs | ~5,000–7,000 lbs |
| 7×12 Tandem Axle | 3,000–4,000 lbs | ~6,000–10,000 lbs |
| 7×14 Heavy-Duty Tandem Axle | 4,000–5,500 lbs | ~9,000–12,000+ lbs |
| 7×16 Gooseneck or Triple Axle | 5,500–6,000+ lbs | ~10,000–14,000+ lbs |
Key Terms to Understand
Before we go further, here are two important terms to keep in mind:
-
Empty Weight (Curb Weight):
The weight of the trailer itself, with no cargo. -
GVWR (Gross Vehicle Weight Rating):
The maximum total weight the trailer can carry, including the trailer’s own weight plus the load.
So, for example, a dump trailer with a GVWR of 10,000 lbs and an empty weight of 3,000 lbs can safely haul up to 7,000 lbs of material.
Factors That Affect Dump Trailer Weight
Several variables affect the actual weight of a dump trailer:
1. Size
-
A compact 5×8 or 6×10 trailer weighs much less than a 7×14 or 7×16 model.
-
Larger trailers mean bigger frames, more metal, and stronger hydraulics—all adding weight.
2. Axle Type
-
Single axle trailers typically weigh less and carry less (usually under 5,000 GVWR).
-
Tandem axle trailers are heavier but offer more stability and payload (7,000–14,000 GVWR).
3. Material
-
Steel trailers are more durable but heavier.
-
Aluminum trailers weigh less but may carry a lower payload and cost more.
4. Hydraulic Components
-
The dump mechanism (scissor lift or single-ram) adds weight—especially for heavy-duty models.
5. Frame and Wall Thickness
-
Heavier-duty frames, reinforcements, and taller walls add significant weight.
Why Dump Trailer Weight Matters
Knowing your trailer’s weight is crucial for several reasons:
1. Towing Capacity
-
You need to know the combined trailer and load weight to stay within your truck’s towing limits.
-
Overloading puts stress on brakes, tires, and the transmission—and is a major safety risk.
2. Licensing & Registration
-
In some states, trailers over 10,000 lbs GVWR may require a commercial driver’s license (CDL) or special endorsement.
-
Weight also affects registration fees and titling requirements.
3. Fuel Economy
-
Heavier trailers require more power, meaning more fuel consumption.
4. DOT Compliance
-
For commercial use, the Department of Transportation (DOT) requires weight compliance, proper labeling, and safety equipment on trailers above certain weight thresholds.
Real-World Examples of Dump Trailer Weights
Here are a few real-world examples to give you context:
| Trailer | Empty Weight | GVWR | Payload |
|---|---|---|---|
| PJ 5×10 Single Axle | ~1,500 lbs | 5,200 lbs | ~3,700 lbs |
| Big Tex 70SR 5×10 Tandem | ~2,000 lbs | 7,000 lbs | ~5,000 lbs |
| Lamar 7×14 Heavy-Duty Tandem | ~4,200 lbs | 14,000 lbs | ~9,800 lbs |
| Load Trail 7×16 Gooseneck Dump | ~5,800 lbs | 16,000 lbs | ~10,200 lbs |
Tips for Choosing the Right Dump Trailer Weight
-
Match the trailer’s empty weight and GVWR to your truck’s tow rating.
-
Leave room for uneven weight distribution or shifting loads.
-
Be mindful of state weight limits, especially for bridge crossings or toll roads.
-
Always factor in the weight of added accessories like tarps, ramps, or toolboxes.
How to Find Your Dump Trailer’s Weight
Here’s how to check the weight of your trailer:
-
Check the VIN Plate or Data Tag:
Most manufacturers include the empty weight and GVWR on the trailer’s VIN plate, usually located on the tongue or frame. -
Consult the Owner’s Manual or Manufacturer Website:
Most brands like PJ, Load Trail, Big Tex, Lamar, and Diamond C publish detailed specs. -
Weigh the Trailer at a Public Scale:
If the plate is missing or unclear, take your trailer to a CAT scale or certified weigh station.
Conclusion
The average dump trailer weighs between 1,200 and 6,000 pounds empty, depending on its size, axle type, and construction.
Understanding your trailer’s unloaded and loaded weight is essential for safe towing, legal compliance, and proper vehicle matching.
Buying a trailer soon? Start by determining your towing capacity and what materials you’ll be hauling most often. Then compare trailer specs to ensure you’re making the right choice for weight, strength, and balance.
Need to double-check your trailer’s specs? Look for the VIN plate or head to a weigh station before hitting the road—and always tow smart.
