What sets the Sportsmobile Promaster RB 111s apart is how seriously it takes insulation and materials, with wool-lined walls, cork underlayment, and radiant barrier foil that keep this ProMaster comfortable in just about any climate. The seating is built to your spec, and the dinettes and gauchos convert from seats into a bed in about a minute, with twin beds that slide together into a Queen. Power comes from a 200-amp AGM battery bank, a smart solar MPPT charger, and a true sine 3000-watt inverter, all with Bluetooth monitoring, so you can boondock without giving up creature comforts. Built on the ProMaster chassis, it drives easily and turns tight, which owners consistently appreciate for both city errands and long hauls.
