Seriously, back off a couple weeks. The last thing the Mexico RV industry needs is some dope, rushing down to claim a beach spot, drive off a road and get killed or injured. Roads and bridges are washed out, power lines are down, flash flooding is just beginning and will last a couple more days.
Official reports are just coming available as teams inspect roads and infrastructure. When buses start running routes, that is when to think about entering the area. Think smart and stay safe.
