Regarding 50amps. We have a 50amp Motorhome, fortunately with just the basic old style power switch box at the entry point in the side bay. We have never had a problem using just 30amp in Mexico. You have to manage your usage and only one AC unit at a time if at all. We carry a couple of fans with us that move the air when needed. We use the fans even when connected to shore power. Our Sola Basic is wired into a 30amp cord and use an adapter at the male end of the 50amp cord. Never a problem! We do carry an extra switch box and Progressive Surge Protect with us when and if needed. As a point of interest when we were staying in Villa Corona Mexico a few years ago, a Huge Motorhome arrived with a Caravan. This rig had 3 (THREE) AC units and had the AC on the entire time. Never checkout how they were doing it, just thought it was weird at the time as we never turned ours on the entire stay. For those who have never been to Villa Corona, cold is be more of an issue than heat.
