The folks over on Tripadvisor say I should probably skip the Sonoran Desert NM. I think I will spend my first night driving from PHX to Ajo and overnight there. See Organ Pipe the next day, then drive to TUS, and spend the next 4 nights there. Looks like I already have enough to see in TUS with my list and some of the other recommendations here. I'll probably skip Bisbee.
Thanks guys!
