The height of an enclosed trailer varies significantly based on its intended use, axle configuration, and overall design, but exterior heights typically range from 7 to 12 feet. The interior height, crucial for determining what you can load, usually ranges from 6 to 9 feet, though custom options can extend even further.
Understanding Enclosed Trailer Height
Determining the ideal enclosed trailer height involves several crucial considerations. It’s not just about clearing bridges; it’s about optimizing space for your cargo, ensuring safe transportation, and complying with local regulations. Let’s delve into the key factors influencing this critical dimension.
Standard Height Ranges
While considerable variability exists, enclosed trailers generally fall into specific height brackets. Single-axle trailers, often used for lighter loads and recreational purposes, tend to be shorter, typically hovering around 7-8 feet externally. Dual-axle and triple-axle trailers, designed for heavier payloads and commercial applications, often extend to 9-12 feet. These figures, however, provide only a general guideline. The type of trailer, such as cargo, motorcycle, car hauler, or specialty build, dramatically influences the final height.
Internal vs. External Height
Distinguishing between internal (inside) height and external (outside) height is paramount. The interior height dictates what you can realistically load and maneuver inside the trailer. A higher interior allows for taller equipment, pallet stacking, and greater headroom for personnel. Conversely, exterior height impacts bridge clearances, overhead obstructions, and potentially wind resistance during travel. Always prioritize knowing both dimensions before making a purchase or rental decision.
Factors Affecting Height
Several factors contribute to the final height of an enclosed trailer:
- Axle Configuration: Trailers with drop axles or multiple axles often sit higher off the ground, increasing the overall exterior height.
- Roof Design: Aerodynamic roof designs might lower the overall height, while raised or rounded roofs can increase it.
- Frame Construction: The thickness and design of the trailer frame contribute to the overall height, especially the floor-to-frame distance.
- Tire Size: Larger tires naturally lift the trailer higher, affecting both the interior and exterior heights.
- Custom Modifications: Customized interiors, roof racks, or additional components can alter the trailer’s height beyond standard specifications.
Measuring Trailer Height Accurately
When verifying trailer height, accuracy is crucial. Use a reliable measuring tape or laser distance meter. Ensure you measure from the ground to the highest point of the trailer, which could be the roof, air conditioner unit, or any other protruding feature. For internal height, measure from the floor to the lowest point of the ceiling, taking into account any structural beams or installed fixtures. Always double-check your measurements to avoid any surprises on the road.
FAQs: Enclosed Trailer Heights Demystified
This section addresses frequently asked questions to further clarify enclosed trailer heights.
FAQ 1: What is the most common interior height for an enclosed cargo trailer?
The most common interior height for an enclosed cargo trailer typically ranges from 6 to 7 feet. This height accommodates most standard-sized cargo items and provides sufficient headroom for average-sized individuals.
FAQ 2: How does the height of the trailer affect fuel efficiency?
Taller trailers generally experience increased wind resistance, which can negatively impact fuel efficiency. A lower profile trailer typically translates to better fuel economy.
FAQ 3: What is the maximum legal height for a trailer in the United States?
The maximum legal height for a trailer in the United States is generally 13 feet, 6 inches (13.5 feet). However, it’s crucial to check state and local regulations, as some jurisdictions may have different limitations.
FAQ 4: Can I customize the height of my enclosed trailer?
Yes, custom trailer manufacturers can build trailers with specific height requirements. This often involves modifying the frame, axle configuration, and roof design. Customization adds to the cost but allows for a perfectly tailored solution.
FAQ 5: Will a higher trailer require a different type of hitch?
The height of the trailer itself doesn’t necessarily dictate the hitch type, but the hitch height will need adjustment to ensure the trailer is level. A drop hitch might be required for taller trailers to maintain a safe and balanced towing setup.
FAQ 6: How does trailer height affect storage options?
Taller trailers provide more vertical space, allowing for greater storage possibilities. Shelving, racks, and vertical storage solutions become more viable options.
FAQ 7: What height should I consider for hauling motorcycles or ATVs?
For motorcycles and ATVs, an interior height of at least 6.5 to 7 feet is generally recommended to allow for easy loading, unloading, and securing of the vehicles. Some taller motorcycles or ATVs might require even more vertical clearance.
FAQ 8: Are there any height restrictions when crossing state lines?
While the federal maximum height is 13.5 feet, it’s always prudent to check the specific regulations of each state you plan to travel through. State DOT websites provide detailed information on height and weight restrictions.
FAQ 9: How does insulation affect the interior height of an enclosed trailer?
Adding insulation to the walls and ceiling of an enclosed trailer will slightly reduce the interior height. Consider the thickness of the insulation when calculating available interior space.
FAQ 10: Does the suspension system affect the overall height?
Yes, the suspension system can indirectly influence the height. For example, using a torsion axle suspension might result in a slightly lower ride height compared to a leaf spring suspension.
FAQ 11: What are the implications of a taller trailer regarding side winds?
Taller trailers present a larger surface area to side winds, making them more susceptible to swaying and instability, particularly at higher speeds. A well-balanced load and proper towing techniques are essential.
FAQ 12: Where can I find the exact height specifications for my specific trailer model?
The exact height specifications should be listed in the trailer’s documentation, which includes the owner’s manual and the manufacturer’s specification sheet. This information can also be found on a sticker or plate attached to the trailer itself, usually near the door or on the frame. Contacting the manufacturer directly is always a reliable way to confirm.
Conclusion
Choosing the right enclosed trailer height is a crucial decision that significantly impacts usability, safety, and overall performance. By understanding the various factors influencing trailer height and carefully considering your specific needs, you can confidently select a trailer that perfectly fits your requirements and ensures worry-free hauling for years to come. Always prioritize safety and compliance with local regulations when making your final choice.
