2020 Mercedes-Benz Sprinter 170 3500 – 9 Seat Family Camper Van Conversion - built for tournament weekends – Sleeps 5–6!
This is a rare, purpose-built family camper van conversion based on a 2020 Mercedes-Benz Sprinter 170WB 3500 chassis designed to function as both a daily driver passenger van and a fully equipped adventure camper. Use it as a weekend camper, your family car or your weekend tournament home!
Unlike most Sprinter builds that sacrifice seating for living space, this van was intentionally designed around families daily and weekend life!

Combined with sleeping capacity for 5–6 people, this makes it one of the most practical family adventure vans in its category.

- Multi-kid households
- Sports travel (teams + gear)
- Outdoor rallies

- Road trips with full passenger capacity
- Daily driver + adventure hybrid use
- Communter/sleep through Van

Daily usable Sprinter chassis
Summary
A low-mileage, detail-built, highly functional family Sprinter conversion with rare seating capacity, designed for real-world flexibility.
Strong fit for buyers needing maximum passenger capacity without sacrificing camper functionality. This is hard to find and took us 5 years to locate then customize to a family of 5.
If you like the layout but don't have a big family, the 2nd row could be taken out and an infinity shower could be added with little water needs. Toilet area is usually added within shower areas so that could free up space and change up that area.
One MaxAirr Fan can be removed and a low wattage A/C unit can be used there for cooling if needed for full time or hotter climates.

Has great reviews and you have two slots to put two in or keep a fan and put one in. Size wise, they are swap out.
This layout is useful and easy to modify if you need something slightly different.
