As far as you paperwork, I bet they registered you correctly based on the fee, but had no way to give an appropriate temp tag for OHV. Go to a 3rd party MVD or wait in line with the unwashed masses ans request a temp tag, to just pay for the needed tags on the spot. Still be way ahead of the full street reg, even if you paid for the OHV twice.
If I wanted to do this, am I missing some paperwork?
All I have is my insurance card from my insurance company, a bill of sale from GoAZ, a "We Owe" statement declaring all payments satisfied, and an ADOT Secure Odometer Disclosure document. No title or lien quasi-title.
I feel like I got more paperwork when I bought my Shadow 2 years ago, but I bought that one cash with no lienholder. And I obviously allowed the dealership to register it as a normal motorcycle.
