Why, why not. Just a few miles north of the park is a big blm area where I stayed the night before. Lots of room and a great T-Mobile signal. Make sure you do what you need to because there is no service in most of the park.
I took the Ajo mountain loop, pay attention to the length restrictions and prepare to spend at least 2 hours driving time. This is a one way loop with a potty 2/3s of the way. Next time I will plan to spend the whole day on the other loop it is a lot longer.
