What Is a Dump Truck & Trailer Combo?
A dump truck and trailer combo is a tandem hauling configuration where a dump truck (typically a 6×4 or vocational chassis) pulls a dump trailer behind it.
Both dump bodies have independent hydraulic systems for loading and unloading. In combination, they can haul up to 30,000–50,000 pounds of material per run—ideal for large-scale work such as hauling asphalt, demolition debris, aggregate, and landscaping fill.
Key Benefits of the Combo Setup
1. Massive Payload Capacity
Combining a truck and trailer effectively doubles your carrying capability compared to a standalone dump truck.
2. Fewer Trips = Lower Costs
More payload per trip means savings in fuel, labor, and time.
3. Operational Flexibility
Hooking or unhitching the trailer allows you to scale capacity as job demands change, all with a single truck.
4. Improved Efficiency
Hydraulic systems on both units save time by allowing simultaneous dumping of truck first, while trailer dumps second.
5. Strong Resale Value
These combos are highly sought after in both construction fleets and resale markets.

Considerations & Drawbacks
- 1. Higher Investment
Purchasing both a dump truck and trailer is more costly upfront than a single dump truck.
- 2. Maintenance Complexity
Two hydraulic systems, dual braking systems, and additional tires and suspension parts increase upkeep requirements.
- 3. Licensing and Regulatory Compliance
Some areas may require special endorsements or commercial regulation due to combined GVWR.
- 4. Space Requirements
Dumping may require more room to maneuver when the trailer is attached.
