Thank you, did my homework and wasn't looking to save money. I am aware that California sales tax is much greater than Arizona's, and prepared to pay the difference upon registration. What I was looking for in the floor plan was only available in AZ (at least the closet to California) after speaking with the dealer he assured me that the vehicle was OK to be registered in California, my mistake was not visually checking myself. At the time I didn't know that the Emissions sticker on the vehicle must specifically say meets California Emissions Standards, not simply Meets US standards. After much research and several calls, turns out that the folks in AZ simply failed to put the correct sticker on t
he vehicle. The Cummings engine family for my rig are ALL certified for California use. I should be getting the sticker next week. Lesson learned, Check, Double Check and then Check again!!
Thank you all for you help and input.
