What Maintainer Corporation does

Maintainer Corporation of Iowa, Inc. is a privately held, family-influenced specialty manufacturer founded in 1976 and headquartered in Sheldon, Iowa, with additional production capacity in Rock Rapids, Iowa. The company designs and builds custom vocational truck equipment — service bodies, lube bodies, welding trucks, and hydraulic and electric cranes (3,000–14,000 lb capacity) — in both steel and aluminum configurations, supported by a portfolio of proprietary technologies including the patented Pressurized Storage System (PSS, installed on ~90% of service bodies), DuaLock aluminum drawer system, Advanced Crane Control (ACC) safety and wireless remote system, and the M-Connect telematics platform that integrates with Samsara, Geotab, and Verizon Connect.

The business serves enterprise customers across construction, agriculture, mining, utilities, railroad, municipal/government, forestry/logging, oil & gas, and equipment dealer verticals, primarily through an independent dealer network across the US and Canada with four regional sales managers and a direct sales team for custom builds. Revenue is generated predominantly through custom-build hardware sales, ship-out crane and accessory sales for retrofitting existing vehicles, replacement parts, an e-commerce accessory storefront (ServiceTruckAccessories.com), and a small but growing recurring telematics subscription stream.

The company is led by President & CEO Shelley Morris with a senior team including CFO Chantell Abshire and VPs of Sales and Engineering. It is ISO 9001:2015 certified and is currently in an investment phase, having expanded its South Plant (effectively doubling manufacturing capacity) and opened an 11,000 sq ft vocational training center and showroom in 2024, while hiring approximately 60 new employees. The MCB rescue truck business was divested to Ward Apparatus in February 2021 to refocus on core service bodies, lube bodies, and cranes, and the company marked its 50th anniversary in January 2026.
