The Short Answer
A reversible minivan camper costs $250 to $1,500 if you build the sleep platform yourself from plywood and reuse camping gear you already own. If you buy a prefabricated conversion kit, a decent portable power station, and a 12V compressor fridge, expect $2,500 to $4,500. Both numbers assume you already own the minivan, which is the whole point. You are not buying a vehicle, you are adding a weekend mode to one.
For context, a rooftop tent alone runs about $1,500 to $4,500. Professional pop-top conversions start around $7,500 on full-size vans, and minivan pop-tops run $16,000 or more. Those are different projects, and we compare them in our minivan vs SUV vs rooftop tent breakdown.
Tier 1: The Bare-Bones Build ($250 to $600)
This is a plywood platform, a foam mattress, and gear from the garage. It is a real camper, and plenty of people never go further.
- Plywood for the deck and boxes: about $120 (one sheet of 3/4-inch, one of 1/2-inch)
- Screws, glue, brackets, sealer, felt strips: about $90
- Ratchet straps and anchor hooks: about $30
- Window covers cut from reflective foam board: about $45
- Battery CO alarm and rechargeable lights: about $65
The mattress is the main swing. If you already have a camping pad that works, you can keep this tier under $400.
Tier 2: The Comfortable Weekend Build ($800 to $1,500)
This is where most people end up after two or three trips. It adds the things that make the difference between surviving a night and enjoying one:
- 4-inch tri-fold foam mattress: about $180
- Sleeping bag rated for your lows, plus a wool blanket: about $160
- Magnetic bug screens and window rain guards: about $125
- Small USB fan: about $30
- Water jugs, basin, and a chuck box galley with stove and cookware: about $175
- Storage bins sized to the platform: about $60
- Fire extinguisher, first aid kit, tire plug kit, jump pack: about $110
Tier 3: Power and Cold Food ($2,500 to $4,500)
The top tier is mostly about electricity. A 500 to 700 watt-hour portable power station with a LiFePO4 battery costs about $300 to $600. A 12V compressor fridge runs about $180 to $400 from budget brands and $800 or more from premium ones, or you can use a good hard cooler for less. A 100 to 200 watt folding solar panel adds about $100 to $300 and stretches your power into a third or fourth day. Buying a prefab platform kit instead of building one usually adds $800 to $2,000 on its own.
Before you spend here, take a few trips. Many people find a good cooler and a small power station cover 90 percent of what they need.
The Costs People Forget
- Campsite fees: free dispersed camping exists, but many weekends end up at a state park or private campground, usually $15 to $45 a night and more at popular parks in peak season
- Host memberships: Harvest Hosts costs $99 to $169 a year, but a minivan only qualifies if it is fully self-contained, including a toilet and a way to collect gray water
- Fuel: a loaded minivan uses more than an empty one, and mountain roads cost more again
- Theft coverage: standard auto policies usually do not cover gear stolen from the car. Homeowner or renter policies may, often with a lower off-premises limit, so check yours
- Tires: extra weight plus gravel roads is hard on tires, which is why the tire plug kit is on the list
Where Not to Save Money
Do not skimp on the CO alarm, the fire extinguisher, or the straps that hold the platform down. Together they cost about $85, and they cover the three things that can actually hurt you. Also, do not buy cheap plywood with voids for the deck. It flexes, it squeaks, and you will rebuild it.
How This Compares to Renting
Class B campervan rentals averaged about $250 a night in the US in 2026, before mileage and fees. A Tier 2 minivan build costs about the same as three to six rental nights, and you keep the car. That is the core of the math, and it is why this build is so popular. For a larger, permanent build, see our cargo van conversion on a budget.
