Kargo Master has been designing and manufacturing commercial vehicle organization systems since 1982, and for more than 40 years has been a standard option for HVAC, plumbing, and electrical contractors specifying new service vans. The company is headquartered in Rancho Cordova, California, where its 50,000-square-foot facility designs and manufactures van shelving, bulkhead partitions, interior drawer systems, and exterior ladder and pipe racks. Kargo Master's HVAC-specific packages come preconfigured with shelving heights, bin layouts, and accessory mounts tuned to how service techs actually stock and work out of their vans.

For an HVAC contractor ordering a new Ford Transit or Mercedes Sprinter, a Kargo Master HVAC package typically includes driver- and passenger-side shelving with parts bins, a bulkhead partition, a ladder/copper rack system, and interior floor protection, all installed through a Kargo Master dealer at or near the time of vehicle delivery. The heavy-gauge steel and powder-coated construction is engineered for the corrosion, torque, and daily-slamming loads that destroy lighter aluminum systems within a few years. Ladder racks like the Kargo Master Drop-Down and EZ-Lo systems let techs safely load 24-foot extension ladders solo without back injuries.

Kargo Master was acquired by Holman in 2018 and now sits alongside Holman's fleet leasing and upfit coordination arm, giving larger HVAC fleet operators a vertically integrated path from lease, to upfit, to maintenance. For small and mid-sized contractors, Kargo Master products are sold through a nationwide dealer network of upfitters like U.S. Upfitters, Elite Truck, and Mid-West Truck Accessories.
