• Fleetwood RVs got their start in Orange County, California. Fleetwood later moved its manufacturing to the city of Riverside, east of Los Angeles, in 1963. The parent company, Fleetwood Enterprises, which also manufactured homes, came to a sad end, filing for bankruptcy in 2009, selling its name and RV division to a New York-based firm that moved operations to Indiana. The 2011 Fleetwood Discovery 40G and 40X share most characteristics, differing slightly in their floor plans and minor components.
