The Sportsmobile Promaster RB 115s is built around a layered insulation system that goes well beyond typical van conversions: cork underlayment underfoot, wool lining on the walls, doors, and ceiling, radiant barrier foil throughout, and magnetic arctic panels for the windshield and doors. That adds up to a genuinely four-season rig. The galley is compact but thoughtfully equipped, with a Norcold 12V fridge, a pull-out faucet, a 10-gallon fresh water tank with city hookup, and a 3,000-watt true sine inverter charger, all managed through a Bluetooth-connected solar and battery system. Seating and sleeping come down to how you spec it out, with dinette, gaucho, and couch configurations available, each converting to sleeping arrangements in about a minute via steel roller track cushion slides. The Ram ProMaster chassis underneath gives the Sportsmobile Promaster RB 115s a tight turning radius and front-wheel-drive confidence that owners consistently praise for both city errands and longer road trips.
