Vans vary in price from low budget to more than the cost of a large sticks and bricks house. DIY camper van conversions can cost from $5,000 to $20,000, plus the expense of the van. If you’re purchasing a new van from a manufacturer, the average MSRP (manufacturer suggested retail price) ranges between $100,000 to $200,000. You can find used class B camper vans for less than $100,000, but that can be challenging since van lifers like to keep their tiny homes on wheels.
