## Overview

A full bath and compact galley give the Sportsmobile Express RB 110s the essentials for comfortable travel without a sprawling footprint. Inside, wool-lined walls, cork underlayment, radiant barrier insulation, and a thermally insulated ceiling help moderate temperatures while reducing road noise. The galley includes a 2.7-cubic-foot 12V refrigerator, sink, 10-gallon fresh-water tank, and pull-out faucet, while the 3,000-watt inverter, solar controller, and 200-amp-hour auxiliary battery system support off-grid stays. Flexible seating and sleeping options can be configured for two, including width-wise beds or a convertible dinette.
