For what it's worth....
I have a class A diesel motorhome registered in Montana and have never had problems to date.
Purchased it used in Camarillo CA (as a resident of Florida). Florida requires the RV to be outside state for the first six months to avoid sales tax with which I complied by immediately traveling to Canada and other states for that period.
Perhaps the original inquirer could solve his situation by registering his automobile in Montana through the LLC company. The attorney I used can certainly provide that for autos, boats and aircraft. Plus the registration fees for most automobiles are usually less there compared to California. The Drivers license "should" not be a problem because we can drive rental autos or borrowed vehicles in other states. (I.e., if challenged, one could explain that he/she are renting the RV/auto from the company.)
Haven't registered my autos in MT yet, but will if issues arise.
I have a distinct aversion to waste . Don't object to paying a fair price for a fair service. Unfortunately, I lived in California for more than 20 years and cannot think of any other state that wastes more money. Moreover, I also owned boats and aircraft which California tried to tax in several ways. In addition to waste, I object to being taxed more simply because it looks as if I can pay more . For some strange reason the concept of equality is totally absent from the Federal and State tax systems .
Good luck,
