Trail King Industries' trailer line includes live-bottom and bottom-dump models, and among the newest of the company's products is the Ultra Lite Series bottom dump. Designed for on-highway service, the Ultra Lite weighs 9,900 pounds and is available in lengths of 36 to 43 feet. Payloads range from 22 to 26 cubic yards. According to Trail King, the trailer's 5-foot by 8-foot 10-inch hopper opening and near-vertical hopper walls ensure complete dumping. Features include an oscillating fifth-wheel plate and lightweight cross braces designed to minimize the flexing in critical areas of stress.
