## Overview

What sets the Sportsmobile Express RB 111s apart is how seriously it takes insulation and comfort. Wool-lined walls, doors, and ceilings pair with cork underlayment and radiant barrier foil to keep the cabin cozy and quiet no matter the climate, with magnetic Arctic panels for the windshield and doors when temperatures really drop. The convertible seating is built to your spec, with twin beds that slide together into a Queen or a couch that sleeps three widthwise, and there's a full bath built into the 19-foot footprint. A robust electrical setup rounds it out, including a 200-amp AGM battery bank, a 3000-watt true sine inverter, and Bluetooth-enabled solar for staying off-grid longer.
