[cwl1979]

From the linked CARB site:

“The Truck & Bus Regulation also does not apply to the following vehicles…:

Motorhomes used for non-commercial private use including vehicles converted to a motorhome. “Motorhome” means a single vehicular unit designed for human habitation for recreational or emergency occupancy and built on, or permanently attached to, a self-propelled motor vehicle chassis, chassis cab, or van, which becomes an integral part of the complete vehicle or a vehicle that exclusively tows a trailer that was originally designed for human habitation for recreational or emergency occupancy.”


Therefore, unless you’re moving (permanently changing resident status) to California, the only regulations/rules that apply are “rules of the road”.  IE- moving or parking violations.  A nonresident just visiting the state does not need to do anything else.

This is what’s current.  It may/may not change in the future.

Read that again. The link i posted says even non residents need to file paperwork and comply
