The large cube doubles are the big brothers to our very successful 550's. While the smaller 550's were designed to maximize load carrying capabilites of 80,000# GVW, the larger 775's can achieve up to 131,100# GVW. With the use of our CNC aluminum router, 24' assisted roll, automatic seam welder, and custom built head press our trailer is the lightest and has the best maintenance history in the industry. These trailers have become the proven workhorse to haul a variety of bulk products.
