Best bet....get a friend with a class B, smarter, safer and cheaper. If you get caught by the troopers, driving out of class that would be bad. If you get into an accident, driving out of class, that would be really really bad. Your trip from CA to AZ is a open invite for Murphy and we all know how he is. Especially if this is your first MV. Bring a cell phone and have cash just in case you breakdown in the middle of nowhere. I took the immigration express from central ca to sac, brought tools and cash just in case. Ended up staying at a hotel for one night, and Murphy struck at a rest stop, turns out the guy I bought the truck from switched the two NEW batteries with TWO OLD batteries, doesn't matter - I still scored a 1970 M35A2 w/winch AND a hardtop for $2k and I drove it home without any issues or problems other than the battery. Good luck.
