The Sportsmobile Express RB 130s stands out for its obsessive approach to insulation, combining cork underlayment, wool-lined walls and ceiling, radiant barrier foil, and arctic magnetic panels for the windshield and doors. That layering makes it genuinely four-season capable in a way most production Class Bs aren't. The galley runs on a 12V Norcold fridge, on-demand water pump, and a 3,000-watt true sine inverter paired with a 100V/50A MPPT solar controller, so you're well set up for off-grid stretches. Sleeping is handled through Sportsmobile's configurable dinette or gaucho system, where seat cushions roll out on steel tracks and drop into a bed in about a minute, with twin setups that can slide together into a Queen bed.
