## Overview

What sets the Sportsmobile Express RB 114s apart from most Class B vans is the obsessive attention to insulation: cork underlayment underfoot, wool lining on the walls, doors, and ceiling, radiant barrier foil throughout, and magnetic arctic panels for the windshield and doors when temperatures really drop. The galley runs on a 12V Norcold refrigerator and on-demand water pump drawing from a 10-gallon fresh tank, with city water hookup available when you're at a site. A 3,000-watt true sine inverter charger with Bluetooth monitoring and a 100V/50A MPPT solar controller mean the Sportsmobile Express RB 114s is genuinely capable off-grid, not just grid-adjacent. Seating converts to sleeping in about a minute via steel roller tracks, and the full bath rounds out a surprisingly complete build for a van you can park almost anywhere.
