3 Horse Slant Load Trailers: Top Things That Make Double D Trailers Stand Out

Standard Features: SafeTack System, SafeBump Roof, SafeKick Wall System

Key Features at a Glance:

  • SafeTack System: Swing-out tack storage for convenience and safety.
  • SafeBump Roof: Impact-absorbing roof to prevent head injuries.
  • SafeKick Wall Systems: Padded walls to protect horses from self-injury.

The SafeTack System revolutionizes tack storage by integrating a fully accessible swing-out tack compartment installed in the back of the trailer. This system improves safety by keeping tack secure and away from horses during transport. By completely swinging to the side, the SafeTack system removes any obstacles that would otherwise intimidate horses during loading and unloading.

The SafeBump Roof System prevents injuries from head collisions by using a flexible material designed to absorb impact. It’s a one-piece design that allows no leaks. Additionally, the composite structure of this roof system lowers the center of gravity, reduces the trailer’s weight, and doesn’t conduct heat which prevents excessive heat inside the trailer. 

The SafeKick Wall Systems protect horses from accidental kicks that might result in injuries. The system uses a durable, shock-absorbing lining to do its job. Additional benefits include less road noise and better insulation of the horse area.

Construction and Materials: Z-Frame Technology, Lightweight Materials

The Z-Frame Technology uses zinc-chromate-infused steel tubing, known for its lightweight, flexibility, and resistance to corrosion. Compared to traditional steel or aluminum trailers, Z-Frame construction ensures durability without adding unnecessary weight. It allows for easier maintenance, improved longevity, increased dependability, and better resale value. 

Lightweight Materials reduce towing strain and fuel consumption, making these trailers a cost-effective choice for long-term use.

Rivet-Free Fabrication: Wherever the design allows it, all slant load trailers built by Double D Trailers utilize the innovative 3M VHB bonding system. It provides flexible seals without the need to drill holes or use rives. This technology prevents corrosion and doesn’t allow for weak points in the trailer’s structure.

Key Benefits of Choosing the Right Construction Materials:

  • Enhanced towing experience and improved safety due to lighter trailer weight.
  • Corrosion-resistant zinc-chromate alloy for better trailer longevity and dependability.
  • Environmentally friendly results due to lower fuel consumption and reduced maintenance needs.

Size and Dimensions: Options for Bumper Pull and Gooseneck

Double D Trailers’ lineup comprises both bumper pull and gooseneck options for their 3 horse slant trailer layouts. The standard size measures 18 feet in length, with gooseneck models featuring an additional overhang space, suitable for storage or sleeping quarters. Interior height options start at 7 feet 4 inches, upgradable to 7 feet 8 inches for larger show horses. The lower trailer weight achieved by utilizing the marvelous Z-Frame technology means that even a half-ton pickup truck can pull a 3 horse slant load gooseneck model, which significantly decreases the weight of the whole composition.

The extended customization plans designed by Double D Trailers allow horse owners to enjoy tailor-made trailers that completely cover or exceed their needs, preferences, and expectations. Popular upgrades include interior linings for added comfort, upgraded flooring with anti-slip and moisture-resistant materials (Rumber flooring), and living quarters for long-distance travel accommodation and convenience.

What is a 3 Horse Slant Load Trailer?

A 3 horse slant load trailer is a type of horse trailer designed to transport three horses at once, utilizing a slanted arrangement for the positioning of the horses. This configuration allows the horses to stand diagonally, optimizing space within the trailer. Although the horses are placed in a slant, they still face parallel to each other and can be oriented either facing forward or backward, giving flexibility in arrangement compared to straight-load configurations.

Now, let's explore how this design translates into specific benefits for transporting three horses.

Benefits of Slant Load Design for Three Horses

The slant load design offers increased space efficiency, enabling more room for each horse without requiring a wider trailer. The additional customization options further enhance this. Horses load diagonally, which reduces stress and creates a more stable center of gravity while on the road. 

The Double D Trailers’ 3 horse gooseneck trailer has an incredibly flexible floorplan that allows for forward-facing or reverse loading. The trailer can also be designed with a double front ‘box’ stall inside the trailer that’s extremely usable during longer events when horses spend a lot of time inside the trailer. 

Common Concerns About Slant Loads

Slant load trailers may limit visibility and access to individual horses during emergencies. Double D Trailers addresses these concerns with innovative designs, such as escape doors, swing-out adjustable dividers, side ramps, and other features that elevate practicality to a whole new level.

Why Choose a Slant Load Trailer for Three Horses?

Advantages of Slant Load Trailers: Space, Safety, and Horse Comfort

Slant load trailers maximize interior space and provide safer, more comfortable transport, alongside easier loading, unloading, and access to each horse. The diagonal positioning reduces weight shifting and helps horses maintain balance on turns.

Disadvantages of Slant Load Trailers: Potential for Imbalance, Turning Restrictions

The slant design can create weight distribution challenges if improperly loaded. Double D Trailers mitigates this risk with reinforced frames and clear loading guidelines. The key factors for safe towing are always the same regardless of the chosen trailer: suitable tow vehicle, proper loading, perfect weight distribution, and consideration of the road and weather conditions.

Steps in Choosing the Right 3 Horse Slant Load Trailer for You

Knowing the right size and dimensions and taking safety factors into consideration are the two most important steps in determining if a 3-horse slant load trailer is for you.

1. Determine the Right Size and Dimensions

Selecting the appropriate trailer size ensures comfort and safety. Interior height and width should match your horses’ dimensions and not the other way around. The trailer’s weight capacity must be aligned with your vehicle’s towing limits – in some cases, your existing pickup truck might not be suitable for towing the trailer you need.

Factors to Consider:

  • Interior Height: It should always be enough to accommodate your horses comfortably, and that’s possible thanks to the available upgrades.
  • Stall Width: The standard stall width of 40 inches should provide optimal comfort for most horses.
  • Weight Capacity: You should always match the trailer’s weight with the towing vehicle‘s capacity to ensure safe and efficient towing.

Key safety elements include towing capacity, manufacturer reputation, and customization options. A well-built trailer reduces risk during transport and enhances overall usability.

Safety Checklist:

  • Verify towing vehicle capacity.
  • Ensure proper loading.
  • Inspect brakes, tires, hitch connection, safety latches, and lights.
  • Opt for safety-enhancing upgrades

What are Alternatives to Slant Load Trailers for 3 Horses?

Straight Load Horse Trailers

Straight load trailers align horses side-by-side, offering plenty of space and visibility for horses, depending on the stall dividers’ design. While ideally suitable for two horses, they are less space-efficient and practical for hauling three or more horses.

Slant Load vs. Straight Load: Which is Better?

The perfect choice depends on individual needs and preferences. Slant load trailers offer more space and stability and easier loading/unloading while straight load trailers provide ease of access and familiarity for certain horses. When you add the plethora of custom options available for all Double D Trailers’ 3 horse models, the slant load configuration becomes the far better choice for its easy and comfortable accommodation, flexible interior and tack space, practical ramps, and so forth.

What DOT Regulations for Horse Trailers Should You Know About?

The U.S. Department of Transportation (DOT) is managed by the Secretary of Transportation.

The inspection includes requirements related to monitoring the technical state of vehicles. A DOT inspection is always performed by federal inspectors who check various aspects such as lighting, brakes, running gear, tires, safety features, hitch components, and more.
