What Is a Fifth Wheel Dump Trailer?

A fifth wheel dump trailer attaches to a heavy-duty pickup truck via a 5th‑wheel hitch mounted in the bed. Unlike traditional bumper-pull trailers, this setup transfers the trailer’s tongue weight directly over the truck’s rear axle, providing greater stability, extra payload capacity, and smoother turning.
These trailers typically come in tandem- or tri-axle configurations and may feature steel or aluminum bodies, hydraulic lift systems, easy-to-use tarp systems, and a variety of gate options.
Advantages of Fifth Wheel Dump Trailers
Superior Stability & Handling
With most weight centered over the truck’s rear axle, you’ll experience less sway, better stopping power, and a smoother ride—even with heavy loads.
Higher Payload Capacity
Without a hitch extending behind the truck, you can legally haul more weight on many estate roads and job sites compared to bumper-pulls.
Better Maneuverability
Fifth wheel articulation allows sharper turning and tighter backing, which is especially useful in construction sites or tight driveways.
Increased Safety
The weight balance and hitch design reduce the risk of trailer sway, especially at highway speeds or during emergency maneuvers.
Versatility
These trailers can haul a wide range of materials—from dirt and gravel to mulch, demolition debris, firewood, and more.

Disadvantages & Considerations
- Requires Heavy-Duty Truck with 5th-Wheel Hitch
You’ll need a truck capable of handling the trailer’s GVWR and equipped with a 5th-wheel setup.
- Less Convenient for Light Cargo
For smaller loads, it may be overkill—bumper-pulls or bed-mounted dump systems may be more practical.
- Higher Purchase and Maintenance Costs
Fifth wheel trailers generally cost more than bumper-pulls and may incur slightly higher maintenance expenses.
- Licensing and Registration
In some jurisdictions, special licenses or registrations may be required.

Key Features to Compare
When shopping, assess these critical features:
1. Material Construction
- Steel is rugged and cost-effective.
- Aluminum offers lighter weight and corrosion resistance but at a premium.
2. Axle Configuration
- Tandem axles (2) are ideal for most light to medium-duty tasks.
- Tri-axle (3) is better for heavier payloads and improved weight distribution.
3. Hydraulic Lifting System
- Check cylinder condition, pumping speed, and absence of leaks.
- Look for serviceable valves and warranty coverage.
4. Tarp System
- Manual-top works fine, but electric or remote-controlled tarts offer faster operation and better load security.
5. Gate Style
- Barn or spreader gates help control flow and unloading.
- Standard high-lift gates maximize volume per load.
6. Suspension & Brakes
- Inspect for steel or air-ride suspensions, working electric brakes, and anti-sway features.
7. Bed Length & Volume
- Shorter trailers (14′–16′) are more maneuverable.
- Longer beds (18′–20′) provide more hauling capacity per trip.
8. GVWR & Tires
- Ensure tires are sized for the GVWR.
- Look for spare tires and heavy-duty rims.
Where to Find Fifth Wheel Dump Trailers
Here are the most common places to locate a trailer that fits your needs:
1. Specialized Trailer Dealers
Many dealers list both new and used trailers, including high-quality fifth wheel models. They often offer inspections and financing plans.
2. Equipment Auctions
Public and private auctions can be excellent places to find good deals on fleet or overhauled trailers.
3. Construction and Landscaping Fleets
Businesses often sell used trailers when upgrading or downsizing fleets. Check with local companies or industry groups.
4. Online Classifieds
Sites dedicated to trailers and equipment (with local filtering) offer a variety of options, often including seller specs and photos.

Safety and Operating Best Practices
- Use Level Ground: Especially when raising the bed to prevent tipping.
- Drive Carefully: Fifth wheel trailers back up differently—practice is key.
- Balance Your Load: Keep heavier material close to the front for stability.
- Watch Overhead Obstacles: Raised bed can hit wires or bridges.
- Secure Your Load: Tarps or straps are essential when on public roads.
Comparison with Other Dump Trailers

- Live-Bottom Trailer: Offers safer unloading via conveyor, but is far more expensive and requires more maintenance.
Fifth wheel trailers offer a balanced blend of high capacity, stability, and towing flexibility with a truck-based platform.
