The real story here is the 48V lithium setup, a 210 amp hour smart battery paired with a 3,500W inverter, dedicated second alternator, and 200W of roof solar means serious off-grid capability without the generator noise. Inside, the Tecnoform high-gloss cabinetry and residential vinyl flooring punch well above typical Class B expectations, and the swivel driver and passenger seats turn the cab into livable lounge space when you're parked. The optional JRide package with Hellwig helper springs makes a noticeable difference on the road, smoothing out what can otherwise be a bouncy ProMaster ride. Add the optional induction cooktop and Timberline hydronic heating and you've got a genuinely four-season-capable rig in a 21-foot footprint with a full bath.
