A few years back a bunch of us were sitting around the campfire outside of Guadalajara, Mexico when this topic came up. While it can be a little more challenging to drive a Motorhome in Mexico, the consensus was 80. Some of the campers had been driving to this campground / area for 30 years and to the best of their memory a friend would turn 80 and not show up the next year. That is my GOAL!
