Can someone redpill me on Arizona?

I'm moving from a Southern state in the heart of Dixie. I've never been North of the Mason-Dixon, and I've never been west of Arkansas and Louisiana. I've been camping, hunting, and fishing since I was a boy. I camp almost every weekend in one of the national forests here.

What am I looking at in terms of camping? How tough is it to get food? Usually I'll just hunt some squirrel, catch some fish, or pick some nuts and fruit. I'm guessing that's not going to happen in a desert.
