Couldn’t be said any better than kaydeejay said it. With a week you’ll barely be able to scratch the surface and you’ll be pushing hard to do that. For example, if you were at the Grand Canyon and wanted to visit the Tombstone area it would be about a 430 mile drive. With that time you’ll have to take the interstates to cover any ground, the worst way to see AZ. But it is what it is. That means I-40 across northern AZ and I-17 north and south. Unless you’re in southern CA, then it would be I-8 or I-10.
I think it would be best to select the places you really want to see, give yourself some non-driving time to see them, and then ask on the forum about the routes to take.
