DET, Deck Over Tilt Trailer

DET-GN Deck Over Gooseneck Equipment trailer

Welcome to Diamond C Trailers, where innovation and durability meet to create superior trailers designed to exceed your hauling needs. We are excited to introduce the redesigned DET, Heavy Duty Deck Over Tilt Trailer, and its gooseneck version, DET-GN. With cutting-edge features and unparalleled performance, these trailers are engineered to deliver the best strength-to-weight ratio in the industry. Our commitment to quality and customer satisfaction shines through in every detail of these trailers, making them the ideal choice for professionals and enthusiasts alike.

Engineered Beam Technology Frame

The revolutionary Engineered Beam Technology Frame is at the heart of our Deck Over Tilt trailers. Our custom U.S. Patent-Protected I-Beams are specifically designed and optimized for each model based on GVWR, length, and other critical factors. This innovation provides unmatched durability and resilience, ensuring your trailer stands up to the toughest conditions. The precise engineering of these beams allows us to maximize the structural integrity while minimizing weight, offering you a trailer that is both strong and efficient. This translates to significant weight savings and increased payload capacity, giving you more room to haul what you need without compromising on safety or performance.

  • Superior Strength-to-Weight Ratio: Our trailers boast the best strength-to-weight ratios of any steel frame on the road. This means they are stronger yet lighter, allowing for more weight savings and a higher payload capacity compared to other trailers. By optimizing the weight distribution, we ensure smoother towing experiences, reducing strain on your vehicle and improving fuel efficiency.

Innovative HD V-Tongue Lid Integration

Our signature HD V-Tongue lid on the Deck Over Tilt bumper pull models is a game-changer. This 1/8-inch thick component with a textured coating adds aesthetic appeal and enhances skid resistance for cargo. It extends the deck space at the front of the trailer, offering unparalleled storage depth. The robust design ensures long-lasting durability, capable of withstanding the harshest conditions and roughest use. Whether you’re hauling heavy machinery or delicate equipment, the HD V-Tongue lid provides the extra space and security you need to confidently transport your load.


Engineered Neck for DET-GN

The new DET-GN, Deck Over Tilt gooseneck trailer features a wider engineered neck, providing more storage space and structural integrity. This neck design enhances the trailer’s overall stability and load-bearing capacity, making it an ideal choice for heavy-duty applications. The gooseneck configuration offers improved maneuverability and towing stability, which is especially important for large and heavy loads. The added storage capacity in the neck area is perfect for storing tools, spare parts, and other essentials, keeping them secure and easily accessible during transport.

Enhanced Hydraulics and Storage

The Deck Over Tilt trailer’s hydraulic system is housed in a 10” x 12” x 53” bolt-on underslung box, freeing up front storage for both bumper pull and gooseneck models. The system includes:

  • Wireless Remote Control: A 4-button remote for hydraulic jacks and a 2-button remote for regular operations, providing ease of use and convenience.
  • Professional Hose Routing: Improved hose routing and securement for a cleaner, more professional look. This setup enhances the aesthetics and reduces the likelihood of damage to the hydraulic lines, ensuring long-term reliability.

New Spare Tire Winch Location

The spare tire is now conveniently mounted between the frame rails underneath the deck, with easy access on the passenger’s side for lowering. This thoughtful design keeps the tire secure and out of the way until needed. By placing the spare tire in this location, we have freed up valuable space on the trailer while ensuring that the tire is easily accessible in case of emergencies. This design choice reflects our commitment to both functionality and convenience, helping you stay prepared on the road.
