What Load King does

Load King is a US-based manufacturer of vocational trailers and heavy equipment, operating as a brand within Custom Truck One Source, Inc. (NYSE: CTOS). Founded in 1956 and headquartered in the Sioux Falls / Elk Point, South Dakota region, the company produces trailers, bucket trucks, dump trucks, water trucks, cranes, service trucks, diggers, chip trucks, rail bodies, roofing conveyors, bumper winches, T-handle remotes, and track equipment. Its differentiated product lines include Voyager (with the AMX+ model featuring increased crane capacity), Outback (with the 28SC-30 electric-operation model), Lightning PTO (with an integrated customer telemetics portal for remote monitoring), and Stinger. Products target field service professionals, utility professionals (electric utility, telecom, rail), and infrastructure project operators.

The business operates through a multi-channel model: a 'world-class dealer network' for sale and rent, direct sales via Custom Truck One Source for new and pre-owned equipment, an online dealer locator, and captive financing through Custom Truck Capital supporting sale, rental, and Rental Purchase Option (RPO) structures. The company markets through social media (Facebook, Twitter, LinkedIn, Instagram), a downloadable product guide/lookbook, and major industry trade shows including The Work Truck Show and WWETT. Recent launches — the Turbo Loader at WWETT 2025 and the Voyager AMX+ / Outback 28SC-30 at The Work Truck Show 2026 — indicate ongoing product investment, particularly into electric-operation capabilities aligned with utility and environmental productivity use cases.

Revenue mechanics are anchored in hardware sales (trailers and vocational equipment), hardware rentals, RPO/lease-to-own financing, and aftermarket parts and service through authorized service centers. The company employs 51–100 people and does not publicly disclose brand-level revenue. As a subsidiary brand of Custom Truck One Source, Load King draws on the parent's public-market access, distribution scale, and captive finance arm while retaining its own dealer-facing brand identity.
