Find Your Ideal 7x16 Double Axle Diamond Cargo Trailer For Sale: Best Deals & Specs

Introduction: Your Ultimate Companion for Hauling

When the need arises for a reliable, spacious, and robust hauling solution, the search can often be overwhelming. For business owners, contractors, motorsport enthusiasts, and homeowners with significant transport needs, the choice of trailer is a critical investment. The 7×16 double axle enclosed trailer consistently emerges as a top contender, offering a perfect blend of capacity, stability, and maneuverability. Among the leading manufacturers, Diamond Cargo has carved out a reputation for building durable and value-packed trailers designed for the long haul.

The Versatility and Value of a 7×16 Double Axle Enclosed Trailer

The 7×16 footprint hits a sweet spot. It’s large enough to accommodate everything from a pair of motorcycles or a UTV to a full load of construction materials or landscaping equipment, yet it remains manageable enough for confident towing in various conditions. The addition of a double axle (also known as a tandem axle) transforms it from a simple cargo box into a stable, high-capacity workhorse, capable of safely handling heavier loads than its single-axle counterparts.

Why Diamond Cargo Stands Out in the Trailer Market

In a competitive market, Diamond Cargo distinguishes itself through a commitment to solid construction, quality components, and accessible pricing. The brand is known for using industry-standard materials and proven building techniques, ensuring that their trailers provide dependable service. From the frame to the roof, a Diamond Cargo trailer is designed to protect your valuable cargo from the elements and the rigors of the road.

What This Guide Will Cover: Specs, Deals, and Ownership Insights

This comprehensive guide will delve into everything you need to know about the 7×16 double axle Diamond Cargo trailer. We will break down its core configuration, explore the details of its construction, and analyze the key specifications that define its performance. Furthermore, we will provide insights into customization options, strategies for finding the best deals, and a clear overview of the purchase process, empowering you to make an informed decision.

Understanding the 7×16 Double Axle Configuration: Power and Practicality

The designation “7×16 double axle” is more than just a set of numbers; it defines the trailer’s core capabilities. This configuration is one of the most popular for a reason, offering a powerful combination of space and strength that serves a wide array of hauling requirements.

The Advantage of a 7×16 Foot Size: Balancing Capacity and Maneuverability

A 7-foot width provides ample interior space for easy loading and maneuvering of cargo, accommodating wider items like ATVs or side-by-sides. The 16-foot length offers substantial volume for tools, equipment, furniture, or inventory without becoming excessively long, which can complicate parking and navigation in tighter spaces. This balance makes it an incredibly versatile choice for both commercial and recreational users.

Why a Double Axle (Tandem Axle) is Crucial for Safety and Load Capacity

The inclusion of a second axle, creating a tandem axle setup, is a critical feature for this size of trailer. A tandem axle distributes the weight of the cargo across four tires instead of two. This significantly increases the Gross Vehicle Weight Rating (GVWR), allowing you to haul much heavier loads legally and safely. It also enhances stability on the highway, reduces sway from crosswinds, and provides a crucial safety net—if one tire fails, the other on the same side can temporarily support the load until you can pull over safely.

Ideal Use Cases: Is This Your Perfect Trailer?

The versatility of the 7×16 double axle Diamond Cargo trailer makes it a perfect fit for numerous applications:

• Contractors & Tradespeople: Securely haul tools, generators, and materials to job sites.
• Landscapers: Transport mowers, blowers, and other heavy equipment.
• Motorsport Enthusiasts: Easily fit motorcycles, dirt bikes, or a single UTV.
• Moving & General Hauling: Handle furniture, appliances, and large household moves.
• Small Businesses: Use as a mobile workshop or for inventory transport.

Diamond Cargo Trailer Construction: Built to Last

A trailer is only as good as its construction. Diamond Cargo prioritizes a robust build, ensuring that each component contributes to the overall strength and longevity of the unit. From the ground up, these trailers are engineered for reliable performance.

Frame and Foundation: The Backbone of Your Trailer

The foundation of any quality enclosed trailer is its frame. Diamond Cargo typically utilizes a strong steel tube main frame and tongue, providing superior rigidity compared to C-channel or I-beam alternatives. This robust structure resists flexing and twisting under load, which is essential for maintaining integrity over thousands of miles. The crossmembers and wall studs are spaced to provide consistent support for the flooring and walls.

Exterior Durability and Design

The exterior of a Diamond Cargo trailer is designed for both aesthetics and protection. Most models feature a semi-screwless or screwed aluminum exterior, which offers a clean look while being lightweight and corrosion-resistant. A stone guard on the front protects the trailer from road debris, and durable aluminum fenders shield the tires. This combination ensures the trailer stands up to weather and road wear.

Walls and Interior: Protecting Your Cargo

Inside, the focus is on protecting your assets. The interior walls are typically finished with high-quality 3/8″ plywood walls. This provides a durable surface that resists dings and scrapes from shifting cargo. More importantly, these plywood walls allow for the easy installation of shelves, E-trac systems, or hooks for securing equipment. The floor is constructed from 3/4″ plywood floors, offering a sturdy and reliable base capable of supporting heavy, concentrated loads.

Key Specifications & Components: A Deep Dive into Diamond Cargo Features

Understanding the specific components of a 7×16 Diamond Cargo trailer reveals the thought and engineering that go into its design. These features work in concert to deliver safety, reliability, and ease of use.

Axles and Suspension: Smooth Rides and Heavy Loads

The heart of the trailer’s hauling capability lies in its tandem axle system. Diamond Cargo typically equips these trailers with two 3,500 lb drop leaf spring axles, resulting in a 7,000 lb GVWR. This axle configuration provides a dependable and smooth ride, absorbing road imperfections to protect your cargo. The “drop” design lowers the trailer’s deck height slightly, making loading and unloading easier.

Wheels and Tires: The Foundation of Mobility

Standard fitment on these trailers includes 15-inch steel wheels, often in a silver or black modular design, wrapped in ST205/75R15 radial tires. The choice of radial tires is significant; compared to older bias-ply designs, radial tires offer better heat dissipation, a smoother ride, longer tread life, and improved fuel economy for the tow vehicle. They are the modern standard for reliable trailer performance.

Braking System: Essential Safety Features

For a trailer of this size and capacity, brakes are not just an option—they are a necessity. A 7×16 double axle trailer from Diamond Cargo comes standard with electric brakes on both axles. This system syncs with a brake controller in your tow vehicle, providing proportional braking power that dramatically reduces stopping distances and enhances control during sudden stops.

Doors and Access: Functionality for Every Need

Diamond Cargo trailers offer functional access points. A key feature is the spring-assisted rear ramp door, which allows for effortless loading of wheeled equipment. The ramp often includes a transition flap for a smoother angle. Additionally, a 32-inch or 36-inch side door with a flush lock provides convenient walk-in access to the cargo without needing to lower the main ramp, which is invaluable for quickly retrieving a tool or checking on your load.

Interior Height: Maximizing Usable Space

Standard interior height for a 7-foot wide trailer is often 6’3″ (75 inches), but one of the most popular upgrades is an increased height to 6’6″ (78 inches) or even 7 feet (84 inches). This extra height is crucial for accommodating taller UTVs, providing comfortable standing room for use as a mobile workshop, or allowing for taller shelving and storage solutions.

Lighting and Electrical

Modern trailers rely on efficient and durable lighting. Diamond Cargo outfits their trailers with a full LED lighting package. LED lights are brighter, consume less power, and last significantly longer than traditional incandescent bulbs. The standard 7-way round plug ensures compatibility with most modern tow vehicles, providing power for tail lights, brake lights, and turn signals.

Customization & Popular Options: Tailoring Your 7×16 Diamond Cargo Trailer

While the standard 7×16 Diamond Cargo trailer is a highly capable unit, one of its greatest strengths is the ability to customize it to perfectly match your specific needs. Tailoring your trailer ensures it functions as an efficient tool for your business or hobby.

Exploring Manufacturer Options and Upgrades

Diamond Cargo and its dealers offer a wide range of factory-installed options. Popular upgrades include:

• Increased Height: As mentioned, adding 6 or 12 inches of interior height is a game-changer for many users.
• Upgraded Axles: For exceptionally heavy loads, you can upgrade to 5,200 lb axles.
• Exterior Options: Choose from a variety of colors, two-tone designs, or a thicker aluminum skin.
• Roof and Wall Vents: Improve air circulation to prevent heat and fume buildup.
• Stabilizer Jacks: Add rear jacks for stability when loading or unloading while unhitched.

Popular Customizations for Specific Use Cases

Beyond factory options, owners often customize their trailers for specific tasks. Contractors might add ladder racks and extensive interior shelving. Motorsport enthusiasts frequently install floor-mounted D-rings or wheel chocks for securing vehicles. For those creating a mobile workspace, adding electrical packages, interior lighting, and insulated walls transforms the trailer into a functional, all-weather environment.

Understanding the Impact of Options on Price

Every customization will affect the final price. It’s important to prioritize options based on need versus want. Functional upgrades like increased height or an electrical package often provide a greater return on investment through improved usability than purely cosmetic choices. Always get a detailed quote that itemizes each option to understand the cost structure.

Finding the Best Deals: Your Smart Buyer’s Strategy

Securing a great deal on a 7×16 double axle Diamond Cargo trailer involves more than just finding the lowest sticker price. A smart strategy focuses on finding the best overall value for your investment.

Researching and Comparing Diamond Cargo Trailers For Sale

Start by browsing the inventory of multiple authorized Diamond Cargo dealers. Pay close attention to the standard features included at each dealership, as some may bundle popular options into packages. Create a checklist of your must-have features and compare the “out-the-door” pricing for similarly equipped trailers to ensure an apples-to-apples comparison.

Tips for Securing the Best Price

Don’t be afraid to negotiate. Inquire about seasonal sales, year-end model clearances, or discounts on in-stock inventory. Sometimes, being flexible on color can result in a better price on an existing unit. Also, consider the cost of delivery or pickup, as this can be a significant factor in the total cost.

New vs. Used: Is a Pre-Owned 7×16 Double Axle Right for You?

A used trailer can offer significant savings, but requires careful inspection. Check for frame rust, axle alignment issues, tire wear, and signs of water leaks from the roof. A new trailer comes with a manufacturer’s warranty, offering peace of mind and assurance of quality. For many, the security and pristine condition of a new Diamond Cargo trailer outweigh the potential savings of a used model.

The Purchase Process: From Inquiry to Delivery

Once you’ve identified your ideal trailer and are ready to move forward, the purchase process is typically straightforward. It begins with clear communication and ends with you taking possession of your new asset.

Contacting the Awesome Sales Team: Initial Steps

The first step is to reach out to the dealership’s sales team. A reputable team will act as a consultant, listening to your needs and helping you confirm that the 7×16 double axle configuration is right for you. They can answer specific questions about the coupler type (typically a 2 5/16-inch ball coupler), warranty details, and the durability of components like the Galvalume roof. This initial conversation is key to building a final quote that includes all your desired options and provides a clear timeline for delivery or pickup.

Conclusion

The 7×16 double axle Diamond Cargo trailer represents a formidable combination of size, strength, and value. Its tandem axle design provides the stability and capacity needed for serious hauling, while its dimensions offer a versatile space for a wide range of cargo. Key construction features like robust plywood floors and walls, a durable Galvalume roof, and reliable radial tires ensure that it is built to withstand demanding use.

By understanding the core specifications, exploring customization options, and employing a smart buying strategy, you can confidently select a trailer that is perfectly tailored to your needs. This isn’t just a purchase; it’s an investment in a tool that can support your business, fuel your hobbies, and make challenging transportation tasks simple and secure. Your next step is to compile your list of requirements, contact a knowledgeable dealer, and begin the process of acquiring your ideal hauling companion.
