2025 Diamond C Trailers 77″X12′ TUBE TOP PSA135 For Sale in Amsterdam, NY

The 2025 Diamond C PSA135 represents a masterclass in utility trailer engineering, designed for those who want a premium towing experience without the bulk of a tandem-axle unit. Whether you are transporting a side-by-side to the trails near Caroga Lake, hauling landscaping equipment through Saratoga Springs, or moving supplies in Ballston Spa, the PSA135 stands out with its ultra-smooth finish and high-strength design. The hallmark of this model is the 4″ engineered channel frame—a feature typically reserved for heavy-duty equipment trailers—which provides incredible rigidity while keeping the trailer light enough for easy maneuvering. Its 2-3/8″ pipe top rail is balled-in and sealed, creating a snag-free surface for your tie-downs and a sleek look that complements any modern truck. From our home base in Amsterdam, we see this trailer as the perfect fit for the Adirondack adventurer or the suburban homeowner who refuses to settle for “good enough” when it comes to their gear.

What is the benefit of the bi-fold gate design on the highway? The bi-fold gate folds in half when upright, which significantly reduces the “parachute effect” or wind drag during travel. This makes for a much quieter tow and better fuel efficiency for your truck compared to tall, flat mesh gates.

What is “Engineered Channel” and why does Diamond C use it? Diamond C uses high-tech lasers to cut and shape the steel channel specifically to handle stress points. This allows the frame to be stronger where it needs to be and lighter where it doesn’t, resulting in a trailer that tows straighter and lasts longer.

How does the Demco EZ-Latch coupler work? The EZ-Latch is a “drop-and-go” system. You simply lower the trailer onto the hitch ball, and it locks automatically. There is no pin to fumble with, making it one of the safest and fastest hitching systems on the market.
