OHV permit for Arizona? (havasu)

I will be taking my rzr down to Havasu next month and was just wondering if I need to buy any kind of Arizona OHV permit for rzr. I live in Nevada and have current Oregon OHV tag. Not sure that will do me any good in Arizona tho.

I will be using the rzr in the desert looking around havasu for some property to buy for a retirement place one day. If anyone local knows of anybody looking to get ride of 5 plus acres of desert hit me up. this trip is more for enjoyment but still plan on scouting out some possible land to buy.
