What Is a Dump Truck Trailer Combo?
A dump truck trailer combo consists of:
- A dump truck (a built-on-frame chassis with hydraulic dump bed)
- A separate dump trailer that hooks behind
Each unit has its own hydraulic system for dumping. Together, they can haul 25,000 to over 50,000 pounds of material per haul—depending on payload configuration. This setup allows you to tackle massive projects with fewer trips.
Advantages of Buying Used
- Cost Savings
Used combos are typically 40–60 % cheaper than new, allowing access to larger rigs at a fraction of the cost.
- Proven Reliability
Equipment already in heavy use has demonstrated performance history—no unknowns waiting to surface.
- Depreciation Benefits
Most depreciation occurs in the first few years. Buying used means retaining higher residual value long-term.
- Available Now
No need to wait months on build times—used rigs are ready immediately, reducing downtime.
| Combo Configuration | Payload Capacity | Price Range (USD) |
|---|---|---|
| Used Dump Truck (6×4) alone | 12k–18k lb | $60,000 – $90,000 |
| Truck + Tandem-Axle Trailer Combo | 25k–30k lb | $130,000 – $180,000 |
| Truck + Tri-Axle Trailer Combo | 30k–35k lb | $170,000 – $240,000 |
| Heavy-Duty 6×6 + Tri/Quad Trailer Combo | 35k–50k lb+ | $220,000 – $350,000+ |
You can expect well-maintained combos from 2015–2020 in the $130k–$200k range. More recent or heavy-duty units command premium pricing.

What to Inspect Before Buying
Buying used means diligence pays. Here’s your checklist:
A. Dump Truck (Tractor)
- Engine & Transmission: Look for smooth starts, no smoke, no slipping.
- Hydraulics: Test lifting full loads; no leaks or slow action.
- Brakes & Air Systems: No leaks, firm pedal feel.
- Chassis & Suspension: No cracked welds or bent frame.
- Tires & Rims: Adequate tread, aligned axles, no bulging.
B. Dump Trailer
- Hydraulics: Full lift/drop cycles under weight.
- Frame & Bed: No cracks or severe rust; tight welds.
- Gate Functionality: Secure latching; sound seals.
- Lights & Wiring: All lights operational, clean connectors.
- Brake Systems: ABS or electric brakes working properly.
- Axles & Tires: Even wear, properly greased bearings.
Common Pitfalls to Watch
- Hidden Structural Damage
Repair shops may have disguised frame or bed damage—look under the frame carefully.
- Electrical Gremlins
Faulty wiring can lead to brake or light failures—inspect plug and harness health.
- Hydraulic Wear
Old cylinders or hoses can leak or fail—new components can be pricey.
- Brake Wear
Brake magnets or drums often overlooked on trailers—test before buying.
- Missing Documentation
No maintenance records can mask serious issues. Always ask for service history and verify clean titles.
Where to Search for Used Combos
1. Truck & Trailer Dealerships
Often stock trade-in units, offer inspections, financing, and some warranty protection.

4. Equipment Brokerages & Online Listings
Trade-specific platforms list combos with specs and sometimes service history.
5. Local Contractor Turnover
Reach out to construction or landscaping companies—they may sell used units in good condition.
Financing & Licensing
- Financing terms typically run 36–72 months through commercial lenders specializing in heavy equipment.
- License requirements vary—dump truck trailer combos may require CDL or commercial vehicle registration, depending on state payload limits.
- Insurance must cover both tractor and trailer, plus cargo and liability.

- Train operators on safe hookup, dumping, and detaching procedures.
