Well. I'm sure ALL the California RV dealers are informing their buyers of this requirement before they will take their money , hitch 'em up, and wave goodby. I brought this up at a local Escapees RVers meeting of about 100 members, with about 50 being 5th wheel owners. No one had this license.
Now all of us not having this license need someone with this license to drive us to the testing site - But there is no one! So you risk impoundment of your rig for going to get the legal license. If you mess up on the pre-trip checkout, or the driving test, you again get to go home without your $70,000 rig. I have contacted RV driving schools, truck driving schools, and RV movers in the area about getting me to the test. They all refused. Can you say Catch 22??? If DMV/CHP really want to get us into compliance, there needs to be an amnesty (politically charged word in this state), or temporary license allowing the current RVers to get to the test by themselves.
The only posting I have heard of on this forum of anyone getting cited for this in California was when they were cited for something else - Towing at 65 MPH instead of the state towing maximum of 55 MPH (which I observe in ALL states I drive in).
I am about to get out of my house and live fulltime in my Bighorn. I will probably stay mostly in California at Thousand Trails parks. But if California goes into hard-XXX enforcement of this very hard to comply with regulation, I will sign up with one of the Florida or Texas mail forwarding services (instead of a California one) and re-register my drivers license and vehicles in one of those states; without California's state income tax, and extremely high vehicle registration fees (or smog checks on diesel pickups - what a joke- there is no electronic testing system for this).
