We are full time RVers that will be part-time in Idaho after August 1, 2019 (escrow closes at that date). Our 2017 Dutch Star's registration is currently in California and is due in May. We are traveling from California to Michigan starting June 1 to visit the Spartan and Newmar factories for warranty service. We do not want to pay the California registration, but can not acquire the Idaho registration until August 1 (proof of residency). Any suggestions on receiving temporary registration from May to August?
