You must live outside of Maricopa county or Tucson, as already mentioned. The problem with using someone elses address, is that all mail that would be related to the DMV will go to that address. Your insurance should show that address as well as your drivers license. Any photo radar tickets would be sent to that address, and it is a pain for the actual resident to get your mail to you in a timely fashion. You do get a different colored tag, and it is checked if you get pulled over, they always ask where you are going and if this is your current address. If you are ever in an accident, you will get to explain the reason you had false info on your license and insurance, and it is likely that your insurance company will drop you for falsifying info to get insurance, and not pay your claims. It is just a matter of time before statewide testing is required, as there are discussions about it now in the northern counties.
I had a so called friend that after being to my house 1 time, took the address from the directions given to him and used it to register his cars... without me knowing it. Not a good move on his part. I particularly did not like the part of the sherriff knocking on my door at 3 am looking for him after he fled the scene of an accident.
Having CA emmissions on your truck doesn't mean it won't pass in Az... you just have to have it all installed and in working order for the visual inspection. If you are missing the parts to make it complete, they can be found at most wrecking yards, there are many F series trucks to choose from.
My 2 cents.
