Silvia and Sergio from Rosario converted a 1995 Mercedes-Benz 1215 bus into a motorhome and have been traveling across South America for over a year. The electrical system includes four 450 W solar panels, a 3000 W inverter with peaks up to 5000 W, and two 200 Ah lithium batteries, powering a refrigerator, washing machine, air conditioning, and full kitchen. A 500-liter water tank and dry toilet are installed. The couple got rid of unnecessary possessions and use the motorhome as their only home.
