Ok so me and Parker Dreamin's plan is this. We both have 2nd homes in AZ. We are buying our boat in CA but leaving the boat and trailer in storage full time in AZ using the boat in AZ full time also. Might bring the boat back 1 time a year for the service in CA. The big question is do we Reg both in AZ? Or just the boat? We have been told reg boat in AZ trailer in CA and then reg both in AZ. HELP PLEASE.............
