I dont really want to get into a big metro area if I can help it...... just need a place to land so I can see whats available...
Christi, Arizona is a big place with a varied climate, so you might want to decide if you want heat in summer or snow in winter, then go from there. But here are some ideas for your future exploring:
Deadhorse State Park - Cottonwood. Good place for exploring the mid-state region, including Flagstaff (snow!) and Prescott.
Fool Hollow SRA - Show Low. The "pine trees as far as the eye can see" area. Again, snow/cold.
Catalina State Park - Tucson. Lots of people like this park. Tucson is a mid-sized city with a variety of housing, and a little cooler than Phoenix.
Lake Pleasant - NW of Phoenix. If you want to explore the Sun City communities west of Phoenix this might be a good perch. And yes, you would have to store your trailer to live in those developments.
