Not sure how far close is for you. Our favorite is 23 miles south at Bisbee. It has WE&S and is over looking very quaint colorful old Bisbee and a huge very colorful pit mine. The ride between the 2 is also very scenic. I believe it is called Copper Queen RV park.
I've seen CGs closer to Tombstone too but specifics escape me right now.
