Check out the "Travel with Keving and Ruth" blog,
http://www.travelwithkevinandruth.com/ They took a great tenting trip this last winter thu Southern Mexico and points further South. You will have to flip back thu the blog to find the trip.
You do have to beware of your stuff left at a tent campsite. A couple of years ago when we were staying in a campground a couple of hours South of Puerto Vallarta a surfer from the USA showed up at the campground in a shook up state. He had been tent camping on the beach a little further South. He was out surfering and when he returned most all of his stuff was gone. He asked to stay at the campground in his tent and was still there when we left a few days later. Believe he was waiting for help from home. We are even cautious when we leave our locked RV.
