## Overview

Sportsmobile wraps the Promaster EB 120s around a Ram ProMaster chassis that owners consistently praise for its tight turning radius, surprising pep, and real-world fuel economy in the 16–17 mpg range. Inside, wool-lined walls, doors, and ceilings pair with cork underlayment and radiant barrier foil panels to create a genuinely four-season interior, not just a marketing claim. A 3,000-watt true sine inverter with Bluetooth monitoring, a 100-watt MPPT solar controller, and 200 amp-hours of AGM batteries mean the Sportsmobile Promaster EB 120s can run independently from shore power for meaningful stretches. The galley covers the basics with a Norcold 12V refrigerator, an on-demand water pump, and both a fresh and grey tank, while the convertible seating, whether a dinette or gaucho, flips into sleeping space in about a minute on steel roller tracks.
