Sportsmobile built its reputation on insulation that most Class B builders don't come close to matching, and the Promaster EB 111s shows that off clearly. Wool-lined walls, doors, and ceiling work alongside cork underlayment and radiant barrier foil to keep the interior quiet and climate-stable year-round, with magnetic arctic panels for the windshield and doors when temperatures really drop. The galley runs on a 12V Norcold refrigerator, on-demand water pump, and a 3,000-watt true sine inverter charger with Bluetooth monitoring, backed by a 200-amp AGM battery system and MPPT solar. Seating converts to sleeping through Sportsmobile's steel roller track system, and the ProMaster chassis itself has earned a strong following for its tight turning radius and approachable driving feel.
