2026 Advanced B Box for Sale

The B Box is Advanced RV's most ambitious platform: a custom box-bodied build on the Mercedes-Benz Sprinter chassis cab that adds roughly nine inches of interior width and stands about 80 inches tall inside (around 6.67 feet of headroom) while keeping a similar exterior width to a normal Sprinter. It also rides higher, with at least 9.5 inches of ground clearance and custom Fox-shocked air suspension. ARV offers it on the 144-inch wheelbase with available all-wheel drive, and on the 170-inch wheelbase as a roughly 24.5-foot, rear-wheel-drive coach whose double-decker design — including a pop-up tent bed — sleeps up to four. Inside it carries ARV's hallmarks: fully insulated, leather-upholstered, furniture-grade plywood cabinets faced in high-pressure laminate with German-spec hardware, a dry bathroom with separate shower, induction kitchen with microwave and freezer, a combination washer/dryer, RGB lighting, and a Sonos system. MotorBiscuit covered it as a roughly $400,000 'tiny home on wheels,' and ARV's own B Box builds have ranged from about $310,000 to $490,000. The honest caution: it is one of the most expensive and most specialized vans you can buy, the tall box body changes the driving feel, and even at four berths it is still a Class B. For a buyer who wants maximum space and capability in the ARV idiom, the B Box is the flagship.
