Robust Dump Sides

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.
