## Overview

A full bath gives the Sportsmobile Express EB 121s a particularly practical setup for a compact Class B, while the movable table lets the interior adapt between meals, work, and downtime. The galley includes a 12V Norcold refrigerator, sink with pull-out faucet, 10-gallon fresh-water tank, and city-water hookup. Wool-lined walls, cork underlayment, radiant-barrier insulation, marine-grade flooring, and Arctic insulating panels help create a quieter, more comfortable cabin in changing weather. Its electrical package adds 200-amp AGM batteries, solar charging with Bluetooth monitoring, LED lighting, and a 3,000-watt inverter charger.
