The McLellan full line of unique water truck bodies are built for the construction, mining and agriculture industries. Each tank is rolled in one piece with only a single, longitudinal weld. This design reduces leakage over tanks welded together in sections, says the company. All McLellan tanks rest on a sub-frame designed for increased surface area, reducing the stress on key sections of the tank for an elongated lifespan. These tanks rest on shock-absorbing hold-down kits and a vulcanized rubber absorption pad system called PermaSlat mounting. These key design features extend the life of the tank from a few years to decades. Trucks range from 1,000 gallons to 5,600 gallons, and are available in multiple configurations best suited to a fleet's needs.
