Model LPT-GN comes standard with a heavy duty 4″ top rail and beefy side upright supports. This is double the thickness of most similar 14K+ dump trailers on the market. Our dumps also feature a central seam overlapped floor design – this intelligent design prevents premature corrosion by keeping moisture out of the corners.

12" Curved Engineered Neck
No welded I-beam sections here – model LPT-GN features our industry exclusive curved 12″ Engineered Neck design. The curves distribute force throughout the neck so there is no concentration of stress in the corners like on traditional goosenecks.
For the ultimate smooth ride and towing experience, add a SHOCKER HITCH air coupler.
Add a Deck on the Neck
The 7′ X 8′ weld-on Deck on the Neck offers additional cargo space for those of you who need every last square inch. Includes clearance lights, rub-rail stake pockets, and up to a 5,000 lb capacity.
