"Out of state" is normally fine. Where you can run into troubles is when you shop your local dealer, buy out of state and try and have it serviced locally. You can be put on the back burner...although I also have dealers that will take anybody anytime, but they also have about 34 service bays.
Most dealers if you are on the road traveling for vacation, that is considered emergency service and they will try and get you back on the road as quick as possible.
