A full bath gives the Sportsmobile Promaster EB 131s a useful level of self-containment in a maneuverable 20-foot Class B. Inside, cork underlayment, wool-lined surfaces, radiant-barrier insulation, and a thermally insulated ceiling help keep the cabin comfortable while reducing road noise. The compact galley includes a 2.7-cubic-foot 12V refrigerator, sink, 10-gallon fresh-water tank, and gray-water tank, while the 200-amp AGM system, solar MPPT controller, and 3,000-watt inverter charger support extended stays. Flexible seating options can convert into sleeping space, including twin beds that slide together into a Queen bed.
