I know you said the Mesa area, but if you are still looking around, check out Desert Trails RV Park out of Tucson. Many activities and friendly people. We liked it so much that we decided to move from OR to Green Valley, AZ. Green Valley isn't Desert Trails, or even very close, but it is still the Tucson area and a great place to live.
