Stayed for a couple of days at Mountain View RV Ranch in Amado, AZ 85645 www.mountainviewrvranch.net
It is easy to get to at exit 48 south of Tucson. Address 2843 E Frontage Rd.
Owners have recently bought campground and are working on updates and repairs. Price for night with all taxes etc is $23.50 for full services. I believe they have rates for weekly and monthly. Spaces are big, easy to pull into. Have cable TV, water, 30amps, sewer, WiFi. They also have laundry and restrooms - which we did not check out. There is a pool and small store in lodge.
Mostly gravel with some little trees and cactus.
Close to Tucson and 25 miles north of Nogales, good overnight for heading in to Mexico through Nogales. A couple of very good restuarants at the off ramp.
