Based on some of the comments above, I think we have been lucky. We bought our Class C at the factory in SoCal. They arranged to have a CDL and ICC licensed driver take it and us to Las Vegas where we signed the final papers and had them notorized. We had a California Transport sticker on the windshield and no plates of any kind, and drove the rig home to Western PA with no difficulty. Arriving home, we went to the local AAA office, paid the sales tax to PA (cheaper than Cal.), paid for and received registration and a plate. Then, took the RV to a local truck service place and had it state inspected (required every year in PA). All done in two partial days.
