The Thor California subsidiary of Thor Industries Inc. recently completed a 50,000-square-foot addition to its fifth-wheel assembly plant in Moreno Valley, Calif., and production in that facility started earlier this month, according to The Press-Enterprise newspaper of Riverside, Calif.

Meanwhile, National RV Holdings Inc. will complete a 164,840-square-foot towable RV assembly plant in Perris, Calif., by the end of October, but that facility will remain idle until market conditions improve, the newspaper reports.

Thor California President Tom Powell said the expansion will create 125 jobs and it will allow the company to increase its output by 25%, or 1,500 to 2,000 units annually.

The unit of Jackson Center, Ohio-based Thor Industries expanded its Southern California operation because of the “vibrant” demand for “toy box” trailers, which have living room in the front and cargo space in the rear for storing motorcycles, all-terrain vehicles and other items for use at camping destinations, Powell told the Press-Enterprise.

However, National RV will not begin production in its new plant in Perris until the company believes it can operate the facility profitably, President Raul Gimenez told the Press-Enterprise.

National RV also will complete a 30-bay service and parts center in Perris later this month, and operations in that facility should begin during December, Gimenez told the newspaper.
