In my experience it's close to impossible to register something like an F150 in California without using a commercial registration. A quick google suggests this experience is widespread. I don't think I have ever seen a F150/250 or Silverado without one in California, ever - easy to spot because the number plates are a different format. There's always been fun debates among car enthusiasts about what you register a Subaru Baja (a strange half-car, half-truck thing) as in California too...
