Choosing the right enclosed cargo trailer is a significant investment, whether for business, recreation, or personal projects. It demands a tool that is reliable, versatile, and built to last. The 8.5×18 double axle Diamond Cargo trailer emerges as a leading contender in this space, offering a perfect blend of size, strength, and adaptability. This guide is designed to be your definitive resource, navigating you through every specification, option, and consideration to ensure you make an informed and confident purchase.

Defining Your Hauling Needs: The Versatility of Enclosed Cargo Trailers

An enclosed cargo trailer is more than just a box on wheels; it’s a mobile storage unit, a workshop, and a secure transport solution all in one. The primary advantage is protection. Unlike open trailers, an enclosed trailer shields your valuable cargo—be it tools, equipment, motorcycles, or inventory—from harsh weather, road debris, and potential theft. This security provides peace of mind, making it an indispensable asset for contractors, landscapers, mobile businesses, and motorsports enthusiasts alike. The 8.5×18 size hits a sweet spot, offering substantial interior volume without being overly cumbersome to tow and maneuver.

Why This Guide: Navigating the Purchase of Your Ideal Trailer

The market for cargo trailers is vast, and the terminology can be daunting for first-time buyers. This guide cuts through the noise. We will dissect the 8.5×18 double axle Diamond Cargo trailer piece by piece, moving beyond a simple list of features to explain the why behind each component. From the structural integrity of the frame to the specific benefits of radial tires and the nuances of customization, you will gain the knowledge needed to configure a trailer that perfectly matches your hauling requirements. We will explore its construction, applications, and the straightforward process of making it your own.

Understanding the 8.5×18 Double Axle: Dimensions, Design, and The Diamond Cargo Difference

Before diving into the finer details, it’s crucial to understand the foundational elements that define this specific trailer: its size, its axle configuration, and the reputation of the manufacturer behind it. These three factors work in concert to create a superior hauling experience.

Decoding the Dimensions: What 8.5×18 Means for Your Cargo

The “8.5×18” designation refers to the trailer’s width and length. An 8.5-foot (102-inch) width is the standard maximum, providing ample interior space to accommodate wide items like vehicles, large equipment, or multiple rows of shelving. The 18-foot length offers a generous cargo area, suitable for hauling everything from a small car or a pair of UTVs to a full load of construction materials. This size is versatile enough for serious commercial use while remaining manageable for experienced personal towers. It provides the capacity for substantial loads without the challenges associated with much longer trailers.

The Indispensable Double Axle Advantage: Stability, Capacity, and Safety

The “double axle” (or tandem axle) configuration is a critical feature for a trailer of this size and capacity. Using two axles instead of one provides several key benefits. First, it dramatically increases the Gross Vehicle Weight Rating (GVWR), allowing you to carry heavier loads legally and safely. Second, it enhances stability by distributing the cargo’s weight over four tires, significantly reducing trailer sway at highway speeds and improving handling. Finally, a double axle system offers a crucial layer of safety; in the event of a tire blowout, the second tire on that side provides support, giving the driver better control to pull over safely.

Introducing Diamond Cargo Trailers: A Legacy of Quality Manufacturing

Diamond Cargo has established a strong reputation for building durable and reliable enclosed trailers. Known for their robust construction standards and commitment to quality materials, Diamond Cargo Trailers are built in their Georgia factory with a focus on longevity. They offer a compelling balance of high-end features and competitive pricing, often achieved through a factory-direct sales model. This approach eliminates unnecessary markups, delivering exceptional value directly to the customer. Choosing a Diamond Cargo trailer means investing in a product backed by a manufacturer that prioritizes structural integrity and customer satisfaction.

In-Depth Features & Specifications: Built for Durability and Performance

A trailer is only as good as the sum of its parts. Diamond Cargo trailers are engineered with high-quality components designed to withstand the rigors of heavy use and challenging road conditions. Here’s a breakdown of the key features.

The Robust Foundation: Frame and Structural Integrity

The chassis is the backbone of any cargo trailer. The 8.5×18 model is built on a heavy-duty steel tube main frame, providing superior strength and resistance to flexing compared to I-beam or C-channel frames. Wall studs and roof bows are typically spaced 16 inches on center, a construction standard that adds significant rigidity to the entire structure and prevents wall warping. The floor is made of durable ¾-inch plywood, capable of handling heavy, concentrated loads, while the interior walls feature ⅜-inch plywood, offering a sturdy surface for securing cargo or mounting fixtures. The use of high-quality screws and welding techniques ensures all these components form a cohesive, durable unit.

Axle and Suspension System: Smooth Ride, Heavy Loads

Supporting the frame are two robust leaf spring axles, typically rated at 3,500 lbs each for a standard 7,000 lb GVWR, with options for heavier-duty axles available. This setup is known for its durability and cost-effective maintenance. Crucially, these trailers come standard with electric brakes on both axles and a battery-powered breakaway system. This is a vital safety feature that engages the trailer’s brakes independently if it ever detaches from the tow vehicle. Easy-lube hubs simplify routine maintenance, extending the life of the bearings.

Wheels and Tires: Reliability on the Road

The trailer rides on 15-inch steel wheels fitted with high-quality Radial Tires. The choice of radial tires is a significant advantage over cheaper bias-ply alternatives. Radial tires offer better heat dissipation for long hauls, a smoother ride, longer tread life, and improved fuel efficiency for the tow vehicle due to lower rolling resistance. This means more reliability and lower operating costs over the life of the trailer.

Exterior Design and Functionality: Protection, Aerodynamics, and Visibility

The exterior is clad in a durable, pre-finished aluminum skin that resists rust and corrosion. Many models feature a V-nose design, which improves aerodynamics to reduce wind resistance and potentially improve fuel economy. A stone guard on the front protects the finish from road debris. For visibility and safety, all lighting is D.O.T.-approved LED, which is brighter, longer-lasting, and consumes less power than traditional incandescent bulbs.

Interior Comfort and Utility: Ready for Any Cargo

Inside, the standard interior height provides ample clearance for most equipment and comfortable movement. A non-powered roof vent helps circulate air, reducing heat and fume buildup. Interior dome lights provide necessary illumination for loading and unloading in low-light conditions. The plywood walls and floor are ready for use as-is or can serve as a solid base for a wide range of custom interior options.

Essential Hardware and Safety Components

Every detail is geared toward security and ease of use. The side door is a sturdy 36-inch model with a reliable bar lock for security, providing quick access without needing to open the main rear doors. The rear ramp door is spring-assisted, making it easy for one person to lower and raise. It’s built to handle heavy rolling loads like vehicles or dollies. Safety chains and a 2-5/16″ coupler are standard, ensuring a secure connection to your tow vehicle.

Ideal Applications: Who Benefits Most from This Specific Trailer?

The versatility of the 8.5×18 enclosed trailer makes it a valuable asset for a wide range of users, from weekend adventurers to hardworking professionals.

Personal Use & Recreation: Hauling Toys, Gear, and More

For the enthusiast, this trailer is the perfect mobile garage. It can comfortably haul multiple ATVs, a side-by-side, a classic car, or a team of dirt bikes. It’s also an excellent choice for campers who need to transport bulky gear, for moving households, or for hobbyists who require a secure space for their projects and materials. The enclosed design keeps expensive recreational “toys” out of sight and protected from the elements during transit and storage.

Commercial & Professional Applications: A Versatile Tool for Business

This trailer is a workhorse for countless businesses. Contractors can transport tools, equipment, and materials securely to a job site. Landscapers can haul mowers, trimmers, and blowers, creating an efficient, organized mobile toolkit. Mobile businesses, such as detailers, pet groomers, or service technicians, can convert the interior into a fully functional workspace. For delivery services, it offers a large, protected cargo bay for transporting goods and inventory.

Customization Options: Tailoring Your Trailer to Your Exact Needs

While the standard Diamond Cargo trailer is exceptionally capable, its true potential is unlocked through customization. Creating a custom trailer ensures it performs exactly as you need it to.

The Value of Customization: Making Your Trailer Uniquely Yours

Customization transforms a generic trailer into a purpose-built tool. Adding specific options can enhance efficiency, improve organization, and increase the trailer’s overall utility and value. By selecting the right features from the factory, you get a professionally installed, integrated solution that is far superior to aftermarket modifications.

Popular Customizations for the 8.5×18 Double Axle

Some of the most requested options focus on improving functionality and durability. E-track systems installed on the floors and walls provide versatile tie-down points for securing cargo of any shape or size. D-rings can be added for heavy-duty anchoring. Upgrading to a higher GVWR with heavier axles is a common choice for those hauling exceptionally heavy equipment. Extra interior height is another popular option for accommodating taller vehicles or creating more vertical storage space.

Exterior Enhancements and Personal Touches

Beyond functional upgrades, you can customize the trailer’s appearance. A wide range of color options allows you to match your trailer to your tow vehicle or company branding. Upgrading to aluminum wheels can enhance the look and reduce weight. You can also choose different styles of doors, such as upgrading the standard side door to an RV-style door with a flush lock for a cleaner appearance and convenience.

The Buyer’s Journey: From Research to Road-Ready

Purchasing your Diamond Cargo trailer is a straightforward process designed to be transparent and customer-focused.

Navigating the Quote Process: Getting Started with Your Purchase

The journey begins by identifying your needs and desired options. You can then request a detailed quote that itemizes the base price of the 8.5×18 double axle trailer and the cost of any selected customizations. This ensures you know exactly what you are paying for with no hidden fees.

Understanding Financing Your Diamond Cargo Trailer: Options and Partners

Many buyers choose to finance their trailer purchase. Reputable dealers partner with lenders who specialize in trailer financing, offering competitive rates and flexible terms. The process typically involves a simple application, and approvals are often quick. Some partners even offer financing options for those with less-than-perfect credit. Payment can often be made through various methods, including financing checks.

The Manufacturing & Quality Assurance Process: What Sets Diamond Cargo Apart

Once your order is placed, it is sent to the Diamond Cargo factory in Georgia. Here, your trailer is built to your exact specifications by experienced craftsmen. The company prides itself on its quality control, with multiple checks throughout the assembly process to ensure every weld, seam, and component meets their high standards.

Pre-Delivery Checks & Inspection: Ensuring Your Trailer Meets Expectations

Before your trailer is released, it undergoes a final, comprehensive inspection. This includes checking that all custom options have been installed correctly, testing all electrical components like lights and brakes, and verifying that the overall build quality is perfect. These final checks guarantee that the trailer you receive is road-ready and meets your expectations.

Delivery & Pickup Options: Getting Your Trailer Home

You have several options for taking possession of your new enclosed trailer. Many customers choose to pick up their trailer directly from the factory, allowing them to inspect it firsthand. Alternatively, nationwide delivery can be arranged, bringing your custom trailer directly to your home or business for maximum convenience.

Maintaining Your 8.5×18 Double Axle Diamond Cargo Trailer for Years to Come

Proper maintenance is key to ensuring your trailer provides safe and reliable service for decades. A consistent schedule of simple checks will protect your investment and prevent costly repairs down the road.

Essential Trailer Maintenance Schedule: Tires, Brakes, and Lights

Regularly inspect your radial tires for proper inflation and signs of uneven wear, which could indicate an alignment issue. Check lug nut torque before each trip. Test your lights—running lights, brake lights, and turn signals—to ensure they are all functioning correctly. Periodically inspect your electric brakes for wear and adjust them as needed for optimal stopping power. Annually, it’s wise to repack the wheel bearings with fresh grease to ensure smooth operation. Keeping the door hinges and ramp spring mechanism lubricated will also ensure they continue to function effortlessly.
