A purpose-built rig, ready for adventures. Our custom 159 wheelbase Promaster campervan features a professional build, upgrades, and custom features from front to back. Unique and flexible build seats and sleeps 1 to 4 comfortably. Everything you need and not much of what you don't. (Back seats can be removed for more room if there are just 1-2 of you.) An upgraded, powerful electrical system is loaded for bear: 2 lithium batteries, 2 solar panels, and a 3000-watt inverter. Luxuries like heated seats and mirrors, cabin heater, digital rearview mirror, electric kettle, microwave, and a KING memory foam mattress are game-changers. See more details below.
