As of 2015, Workhorse does not produce its own recreational vehicle units. According to a news statement from the company, Workhorse Group Inc. plans to return to the RV manufacturing industry with production centered at its manufacturing plant in Workhorse Union City, Indiana. The planned Workhorse RV chassis is available with two engine options, which are 6.0 and 8.8 liter gasoline engines coupled with an Allison-brand transmission system.
The 8.8 liter version of the Workhorse RV chassis' design matches the mileage and towing ability of a comparable diesel engine. Workhorse was known as an industry leader for RV chassis manufacturing during the mid-2000s, but it ceased production after the RV market declined between 2007 and 2009.
AMP Electric Vehicles acquired the Workhorse brand and its Indiana assembly plant in 2015. With the acquisition, AMP Electric Vehicles also decided to change its formal business name to Workhorse Group Incorporated. Prior to this acquisition, the brand operated as a division under Navistar.
The acquisition deal between Navistar and AMP Electric Vehicles also included a network of over 400 dealers around the United States. In addition to its Indiana plant, the Workhorse Group also operates a 50,000 square feet battery design and production facility for its chassis in Loveland, Ohio.
