The widely popular 3D (Drop-Deck & Dump) model is the world’s only trailer of its kind – offering the dual-purpose flexibility of being both a drop-deck and dump trailer all in one heavy-duty vehicle. With a full 149? internal deck length and 74? deck width combined with a 10,000lb equipment capacity (8,000 dump capacity), you can fit most any piece of equipment to handle just about every job, large or small.
