Eddie...
I wasn't going to say anything until I saw the word "safety" in your posting. I figure (most) folks are, to a certain degree, somewhat aware of what's going on in Mexico and can make their own decisions. I've been a San Diego police officer for more than 30 years. I fly a police helicopter along the border every night and I receive regular intelligence briefings from the DEA, other law enforcement agencies and my own department on what's going on throughout Mexico. I'm not paranoid about what's going on south of the border, but I am aware.
My wife (also in law enforcement - a Deputy District Attorney) and I used to fly our plane deep into Baja to visit various resorts. When we sold the plane and bought a motorhome, we used to take it down there. We traveled with our kids and other RVers and had a great time. Corruption and drug-related hazards have always plagued Mexico and, like now, we were aware of the risks, but I can't emphasize this enough... The risks then (15 years ago) were NOTHING compared to what they are today. You don't have to go looking for trouble in Mexico to find it. You're only hearing what the news is telling you.
I fully realize that a lot of RVers have been going to Baja and other Mexican zones for years, and they haven't had any problems (I never had any problems). They're probably reading this, thinking, "Ahh... I've never had any problems down there." or "I know where to go to stay out of trouble." That's fine. I certainly understand why they'd feel that way and why they go there. Many services and prescriptions are cheaper, it's a laid-back, easy going environment and it's just plain fun. But don't think for a second that the risks associated with RVing in Mexico today are the same, or only slightly more than they were years ago. They are much greater today, as our intelligence briefings constantly remind us. There are reasons why the State Department has put much of Mexico on their travel-warning list, and there are reasons why the cruise-ship industry has, to a large degree, stopped going to many ports in Mexico.
If someone insists on RVing to Mexico, there are a few things they could do to reduce their exposure to some of the risks. Travel in as large a group as possible, travel only in the daytime, and visit the State Dept's website for the latest list of hot spots and stay away from them. Of course that's in addition to having an insurance policy that the Mexican Govt recognizes. Many people don't know that some US-based insurance policies aren't recognized by the Mexican Govt. Your policy may say that it covers you while RVing in Mexico, but the Mexican Govt. doesn't recognize it. They want you to buy THEIR insurance. It's just another way of getting money - but that's another topic.
I've seen the topic of RVing in Mexico come up before, but the people posting weren't asking anyone's opinion on whether or not it was "safe" to go, they were just going. You asked, so as a fellow RVer with current and specific knowledge of the risks, I felt obligated to answer your question. Best of luck.
