Favorite RV Park in the AZ mountains?

Not many trees though.

Dead Horse Ranch State Park in Cottonwood. Hiking, biking, fishing, horseback riding, great views. On the Verde river. Lots of stuff to do. A little hot right now (95-100). You can view the sites on their website. PO about 3 miles.

If you are wanting to be in the mountains, the cooler part of AZ in the summer with the parameters that you have I would suggest Fools Hollow Lake State Park.

Any of the Maricopa County Parks would suit you, along with most County Parks in the State! About the only thing they are lacking is sewer hook-up, but they have dumps.

Mt Lemmon outside Tucson. Mt Bigelow is dispersed camping in the woods with a few sites to fit an RV. No water, restrooms, or hookups, but it is free. Other campgrounds are fee. Rose Canyon Lake has been a favorite since I was a kid. Has a couple of a RV loops. All close for winter end of Oct. Town of Summerhaven is at the top (close by), as is Tucson. It is Coronado a National Forest so there are consecutive day stay limits (14 days).
