"More Trailer For Your Money"

7 x 14 Diamond C GTU 235 7K Utility Trailer – Ready To Work!

The Diamond C GTU 235 (General Tandem Utility) is the tandem-axle "big brother" to the PSA series. While it keeps the user-friendly features of a utility trailer, it moves into a 7,000 lb GVWR class, making it a professional-grade workhorse for hauling heavier mowers, side-by-sides, and construction materials.

KEY STANDARD FEATURES 4" Engineered Channel FrameUnlike many tandem utility trailers that use standard angle iron, the GTU is built on a 4" Engineered Channel Frame. This provides a rigid, professional-grade backbone that prevents the "frame twist" often seen in cheaper trailers when one side is loaded more heavily than the other.

**7,000 lb GVWR (Dual 3,500 lb Axles)**The "235" package denotes dual 3,500 lb axles, both equipped with electric brakes. For 2026, these are typically Lippert Super Lube axles with 5-leaf slipper spring suspension, offering a much smoother tow and better weight distribution than a single-axle setup.

EZ Bi-Fold Ramp GateStandard on the GTU is the EZ Bi-Fold Gate. It’s spring-assisted for "one-finger" operation and folds in the middle to stay below the truck’s slipstream.

• The Benefit: It drastically reduces wind drag and "parachute effect" while towing empty, saving you significantly on fuel or battery range.

**2-3/8" Pipe Top Rail (Balled-End)**While many competitors use thin square tubing or angle iron, the GTU features a 13-gauge Pipe Top Rail. It is significantly more resistant to bending and serves as a continuous, heavy-duty tie-down point for hooks and straps along the entire perimeter.

10" x 13" Lockable Steel Tongue BoxEvery GTU 235 comes with a built-in storage box integrated into the tongue. It’s lockable and weather-sealed, perfect for keeping your chains, straps, and hitch pins secure and out of the elements.

Under-Frame Spare Mount with Cable WinchTo keep the bed area clear and the sides looking sleek, Diamond C uses a Retractable Cable Winch spare mount tucked under the frame. It functions exactly like a pickup truck's spare tire system, keeping the tire protected from UV damage and out of your way until you need it.

2" - 10,000 lb Demco EZ-Latch CouplerEven though the trailer is rated for 7,000 lbs, it comes with a 10,000 lb rated Demco EZ-Latch. This adjustable-height coupler automatically latches when dropped onto the ball, ensuring a safe, "no-guesswork" connection every single time.

PERFECT FOR

The GTU 235 is the perfect choice for commercial landscapers running two zero-turn mowers, off-roaders hauling a 4-seater side-by-side (UTV), or property owners who need a multi-purpose trailer that can handle a load of gravel just as easily as a tractor.

The Diamond C Advantage: Why choose the GTU 235?- THE WARRANTY 2.0: As with all 2026 Diamond C models, you get the 6-Year Structural Warranty and the 2-Year Comprehensive (Bumper-to-Bumper) Warranty. Most tandem utilities from competitors come with a 1-year limited warranty; Diamond C doubles that for components and doubles it again for the frame.

• DM Difference Maker Coating: Utility trailers are notorious for rusting at the welds within two seasons. Diamond C’s 6-step powder coat process with Zinc-Rich Primer prevents the "bleeding" rust common on utility trailers, ensuring it looks professional for years and holds a massive resale advantage.
• Integrated Tie-Downs: You get Integrated Upright Tie Downs and 5 standard stake pockets. You aren't hunting for a place to hook a strap; the trailer is designed with multiple securement points built into the structural uprights
