We probably won't be doing the same trip you are planning (but you never know). But we can make some suggestions. Essential guide - Travelers Guide To Mexican Camping by Mike & Terri Church - often referred to as "The Church Book" - and their website . . . http://rollinghomes.com/Update%20log.htm . . . with updates to the book. Roam around the website to learn lots more.
See the "Stickies" at the top of this forum and study the info found there.
By the way - I grew up just outside NYC and lived on Vieques, PR for 8 years.
If you are into ancient ruins as we are there is a Wiki list of the ruins of the world - see web address below - with list of sites in Mexico. We have visited quite a few of these and forget many of them. We have read the pyramid at Cholula near Puebla is the largest in the world by volume and the Pyramid of the Sun at Teotihuacan is the third largest by volume. Now that there are new roads around Mexico City you can get to Teotihuacan and Puebla without going through Mexico City traffic. Sites like Chichen Itza and Tulum can be overwhelmed by tourist buses and venders selling junk souvenirs - get there when they first open in the morning and you might be able to beat the crowds. Off the top of my head our favorites are Palenque, Teotihuacan, Uxmal, Ek' Balam. You can research all of these sites online. Here is the wiki list of sites in Mexico - with some of the majors and our favorites in UPPER CASE.
