AZ is probably the easiest state to register a Roxor. I probably bought the 5th or 6th Roxor in AZ, and supposedly 2 or 3 of those went out of state. So maybe 3rd or 4th registered in AZ and it wasn't hard at all.
You shouldn't / wouldn't leave the dealer unless you pay full VLT. It weighs over 1,800 lbs so you are not escaping paying full use tax like any other road vehicle. The only thing they should ask you to do at MVD or 3rd party reg office is sign the affidavit you have license plate light because at bare minimum you already have everything else. And insurance.
Lessons learned, AutoZone/Oreilly's/Pep Boys sell an inexpensive license plate holder/LED light. Get that one! Don't go to Ride Now and get the "UTV kit" one. It's like $10 vs $50. I made my own and it was like $20. Should have looked 1st.
Caveat, windshield, just get one. One cop will interpret the law differently from another. Plus its better than goggles. The one at Nash is recommended unless you want to buy my CJ5 older style hinge, Roxor ready as it is.
Turn signals, not required by law but I recommend it. Less people flip you off. I rolled my own for under $50, but I had the lights. I've been perfecting it since.
Once registered, insured, windshield highly recommended, and turn signals (recommended not mandatory by law) you can drive it anywhere in AZ. Get the ECU flashed to eliminate the 45/55 MPH limiter and yes you can drive it on the freeway IN ARIZONA. It drives like any BRAND NEW leaf sprung non-ABS Jeep on the road.
