## Overview

The Sportsmobile Sprinter RB 131s is built on a Mercedes Sprinter diesel chassis and drives more like an SUV than a motorhome, with a 9-speed automatic and a tight enough footprint to park almost anywhere. What sets the Sportsmobile apart is its layered insulation system: cork underlayment underfoot, wool-lined walls, doors, and ceiling (zero outgassing, mold-resistant), radiant barrier foil, and magnetic Arctic Insulating Panels for the windshield and doors. The electrical setup is equally serious, with a 200Ah AGM auxiliary battery system, a 3,000-watt true sine inverter/charger, and a smart MPPT solar controller, all manageable via Bluetooth. A Norcold 12V refrigerator, pull-out faucet sink, city water hookup, and a full bath round out a genuinely livable galley and bath package in a 19-foot coach.
