Assessing Your Hauling Needs: The Foundation of Your Choice

Before diving into the specifics of trailers, it’s crucial to understand your own hauling requirements. This foundational assessment will guide your decision-making process and ensure you select a trailer that perfectly aligns with your needs. Consider using a spreadsheet to document your needs and compare trailer options effectively.

What Exactly Are You Hauling?

The nature of your cargo will dictate many of your trailer choices. Are you transporting delicate electronics, rugged construction materials, or perhaps a prized classic car? Consider the dimensions, weight, and fragility of your typical cargo. For example, transporting motorcycles might require specific tie-down points and a ramp with good traction, whereas hauling furniture might necessitate a taller interior height. Transporting temperature-sensitive goods may require insulation and climate control considerations.

Quantifying Your Cargo: Size, Weight, and Volume

Knowing the precise dimensions, weight, and volume of your typical cargo is essential. This information directly impacts your trailer’s required payload capacity and interior dimensions. Measure your largest and heaviest items to ensure they’ll fit comfortably within the 6×12 footprint. Remember to consider the combined weight of all items you intend to haul simultaneously. Use online calculators to estimate volume and ensure you have sufficient space.

Frequency and Purpose of Use (e.g., Professional, Hobby, Personal)

How often you plan to use the trailer and for what purpose will also influence your choice. Professional users may prioritize durability and maximum payload capacity, while hobbyists might prioritize specific features like interior lighting or sidewall vents for ventilation. Personal use might necessitate a balance of affordability and functionality. For example, a landscaper might require daily use and prioritize heavy-duty axles, while a weekend camper might prioritize lighter weight and fuel efficiency. Consider the long-term cost of ownership, including maintenance and potential upgrades.

Considering Your Towing Vehicle’s Capabilities

A critical factor is your towing vehicle’s capabilities. Every vehicle has a specified towing capacity, and exceeding this limit can be dangerous and damage your vehicle. Consult your vehicle’s owner’s manual to determine its towing capacity and ensure the fully loaded trailer weight, including the trailer itself and all cargo, falls within this limit. Remember to factor in the tongue weight, which is the downward force exerted by the trailer tongue on the towing vehicle’s hitch. Using a weight distribution hitch can help improve stability and control when towing near your vehicle’s capacity.

The Power of Tandem Axles: Stability, Capacity, and Safety

Tandem axles are a game-changer for hauling heavier loads. They provide a significant upgrade in stability, capacity, and safety compared to single axle trailers. This improved performance comes from distributing the weight and braking force across four tires, enhancing control and reducing strain on the towing vehicle.

Enhanced Load Distribution and Stability

With four tires bearing the load instead of two, tandem axles distribute the weight more evenly, leading to increased stability. This reduces sway and bounce, especially at higher speeds or on uneven road surfaces. Imagine carrying a heavy box with one hand versus two – the two-handed approach (tandem axles) provides significantly greater stability. This is especially noticeable when navigating curves or encountering crosswinds. Tests have shown tandem axle trailers demonstrate up to 20% less sway compared to single axle trailers under similar load and wind conditions.

Increased Payload Capacity

Tandem axles allow for a higher payload capacity compared to single axles. A 6×12 tandem axle enclosed cargo trailer can typically handle a payload of around 5,200 lbs, significantly more than the approximately 2,300 lbs capacity of a single axle counterpart. This expanded capacity makes them ideal for hauling heavier equipment or larger quantities of materials. Tandem axle vehicles can also transport 30% more weight on rough terrains without compromising stability. For instance, a contractor could carry a full load of bricks or lumber, maximizing each trip and reducing overall transportation costs.

Improved Braking Performance

The braking system is significantly enhanced with tandem axles. Electric Brakes on both axles provide superior stopping power, which is essential when hauling heavy loads. This is particularly crucial for safety, especially in emergency situations. Having brakes on both axles distributes the braking force, reducing the stopping distance and minimizing the risk of jackknifing. This is particularly important when descending steep grades or navigating slippery road conditions. Studies show that tandem axle trailers can reduce stopping distances by up to 15% compared to single axle trailers under heavy load conditions.

Navigating Different Terrains and Road Conditions

Tandem axles offer improved performance on various terrains. The additional tires provide better traction and stability on gravel, dirt roads, or uneven surfaces, making them more versatile for different hauling environments. The reduced ground pressure per tire also minimizes the risk of getting stuck in soft ground or damaging delicate surfaces. This is particularly advantageous for contractors working on construction sites or landscapers accessing remote properties.

Key Features to Consider for Your 6×12 Enclosed Cargo Trailer

Now that we’ve established the advantages of tandem axles, let’s explore the specific features that contribute to a perfect 6×12 enclosed cargo trailer. These features can greatly influence the functionality, durability, and safety of your trailer.

Trailer Dimensions and Interior Height

The 6×12 footprint offers a balance of space and maneuverability. Interior height is a crucial factor, with common heights being 6’3″ and 6’6″, impacting your ability to transport taller item. Consider your cargo dimensions and whether you need the extra headroom. Enclosed trailers are expected to grow at the highest CAGR in the trailer market because they offer maximum storage space with customizable interiors. Ensure you measure your cargo and compare it to the interior dimensions to avoid any surprises. Consider future needs as well – will your cargo size change over time?

Payload Capacity and Axle Ratings

Payload capacity is the maximum weight the trailer can safely carry, directly related to axle ratings. Ensure the trailer’s payload capacity meets your hauling needs. Carefully consider both the gross vehicle weight rating (GVWR) and the trailer’s empty weight to determine the actual payload capacity. Remember to factor in the weight of any added accessories or modifications.

Braking Systems: Essential for Safety

Electric brakes on both axles are crucial for safe and controlled stops, especially with heavier loads. Ensure your braking system is up to the task. “The tandem axle option also includes an individual braking system in each axle to help ensure the additional weight can stop safely”. Consider a break-away kit for added safety, which automatically engages the trailer brakes if it becomes detached from the towing vehicle. Regularly inspect and maintain your braking system for optimal performance.

Tires and Wheels: Durability and Performance

Radial tires are generally preferred for their durability, load-carrying capacity, and smoother ride. Aluminum wheels offer a good balance of strength and weight savings. Consider the load range of your tires, ensuring it matches your trailer’s GVWR. Investing in high-quality tires can significantly improve fuel efficiency and reduce the risk of blowouts. Consider a tire pressure monitoring system for added peace of mind.

Entry and Exit: Doors and Ramps

A rear ramp door provides easy loading and unloading for a wide variety of cargo. A side door offers convenient access to smaller items without needing to open the entire ramp. Ramp & ramp flap features can enhance the loading process further. Consider the ramp’s weight capacity and angle for loading heavier items. A spring-assisted ramp can make loading and unloading easier, especially for heavier equipment.

Exterior Construction and Aesthetics

A semi screwless exterior offers enhanced durability and a sleek appearance, reducing potential leak points. A blackout package enhances aesthetics and protection. Options like Covered Wagon branding may add to the value and signify quality. Consider the material thickness and gauge for added durability. A protective coating can help prevent rust and corrosion, extending the life of your trailer.

Plywood walls and a plywood floor provide a durable and customizable interior. LED Lights and a Dome light enhance visibility, while Sidewall Vents provide ventilation and moisture control. Consider adding E-track or D-rings for securing cargo. Insulation can protect temperature-sensitive items and reduce noise during transport.

Lighting and Electrical Systems

Adequate lighting is crucial for safety and visibility. LED light packages offer bright, efficient illumination, enhancing safety during nighttime towing and loading/unloading. Check that all lights are functioning correctly and meet DOT regulations. Consider adding interior lights for convenience and exterior marker lights for added visibility.

Chassis, Frame, and Suspension Components

A robust chassis, frame, and suspension are essential for safe and reliable towing. Look for strong construction and features like EZ lube hubs for easy maintenance. Consider the type of suspension, such as leaf spring or torsion axle, based on your hauling needs and budget. A heavier-duty suspension will provide a smoother ride and greater load capacity.

Safety Features Beyond Brakes

Safety chains are a legal requirement and provide an added layer of security in case of trailer separation. Tongue jacks facilitate easy hitching and unhitching. Consider adding a coupler lock for theft prevention and wheel chocks for added stability when parked. Regularly inspect your safety chains and coupler for wear and tear.

Interior Height: Maximizing Your Vertical Space

Interior height directly impacts the types of cargo you can transport. Consider whether you need to stand inside the trailer or transport taller items when choosing your interior height. Measure your tallest cargo item to ensure it will fit comfortably, and remember to account for any additional racking or shelving you might install. Choose an interior height that maximizes your space utilization without compromising towing stability.

Payload Capacity: Knowing What You Can Safely Carry

Payload capacity is a crucial factor in your trailer selection. Always prioritize safety and never exceed the specified limit. Accurately calculate the weight of your cargo, including any packaging or palletizing materials. Regularly weigh your loaded trailer to ensure you are within the safe operating limits. Overloading can damage your trailer, towing vehicle, and put you and others at risk.

Axles with Brakes: Ensuring Controlled Stops

Electric brakes on all axles are a non-negotiable safety feature for tandem axle trailers, ensuring reliable stopping power under heavy loads. Regularly inspect and maintain your brakes to ensure optimal performance. Consider upgrading to higher-capacity brakes if you frequently tow near your trailer’s maximum capacity. Ensure your towing vehicle is equipped with a brake controller that is compatible with your trailer’s braking system.
