Moving to AZ in June next year, 2015 Jeep Wrangler Rubicon (well modified) and 2018 Winnebago class C motorhome will come with us and are registered in Iowa with clear titles, maybe I will keep them plated in Iowa as I still own property there and visit frequently but by airplane. Might this be an issue? Will trade my company car on a Toyota Highlander just before we leave Iowa and intend on plating in AZ I presume 90 days-ish after we arrive?? What are the issues with leaving some vehicles plated back home? Any thoughts / experiences?
