HWH Corporation manufactures a wide variety of hydraulic and pneumatic equipment for trailers, RVs, buses and numerous other types of vehicles. The company first began producing hydraulic leveling systems and air leveling systems for the RV industry, later expanding to produce many other hydraulic products, including hydraulic slide-out systems, hydraulic pocket door systems, hydraulic bed lift systems, hydraulic exterior step systems and hydraulic saddle rack systems.
In addition to trailers and RVs, the company also produces hydraulic and pneumatic systems for Class A, B and C motorhomes, communication vehicles, and broadcast vehicles. Other types of vehicles for which HWH manufactures equipment include emergency vehicles, fifth wheel trailers, horse trailers, toy haulers and safety vehicles.
Founded in 1967, HWH originally manufactured hydraulic equipment for agricultural companies such as Caterpillar and John Deere before switching to focus on RV leveling systems in 1984. The company designs, manufactures and assembles approximately 99 percent of all its own parts at one of its three production facilities in eastern Iowa. HWH has two facilities in Moscow, Iowa, and one in Wilton, Iowa. The company's headquarters are in Moscow, Iowa, which is where HWH Corporation has been located since moving its operations from Illinois in 1979.
