From Pepe's you you take the periferico South until you get to Insurgentes Sur, that takes you to the toll road to Cuernavaca, there is a hairpin curve to the right mid way down the mountain that needs to be taken slow, go past Cuernavaca and take the toll road to Acapulco there is a town mid point that is Iguala, normal gas stop for most vehicles.
The periferico in Mexico City originally was a two lane on the center roadway and two lane on the lateral, some years latter they made both roadways three lanes, if you survive the transit on the periferico with out geting into an accident or scrape, you are lucky.
The Estado de Mexico and the Distrito Federal have the "hoy no circula"
that you need to be aware off, depending on the last number of the licence plate is the day that the vehicle does not move, and all foreign behicles do not move on Saturdauys, on days that the vehicle can move there is a time restriction from 05:00 AM to 11:00 AM when all foreign vehicles do not circulate, driving a big RV on the periferico is not advisable, you need to straddle two lanes so that the microbuses do not tear the mirrors off, and Mexicans suffer from "yo primero" me first and they get pissed when you go slow and hog lanes, as soon as they can they pass, cut you off and slam on the brakes.
