Converting a 2018 Honda Odyssey into a Family Campervan

In 2021 our kids were small enough that we could fold them anywhere, but old enough to want adventure. We had a 2018 Honda Odyssey, a few weeks of vacation, and a long list of national parks we wanted to see. Hotel rooms at park entrances cost more than they’re worth and don’t get you close to anything. A rooftop tent felt impractical with a toddler. A full van conversion was more than I wanted to take on.

So I converted the Odyssey.

A minivan is an underrated campervan base. It fits in a normal parking spot. It gets reasonable fuel economy. The sliding doors give you a kitchen entrance that no cargo van can match. And a Honda Odyssey has enough interior volume that, with the seats removed and a platform built, you get a sleeping space that comfortably fits two adults and two young kids.

This is a writeup of everything in the build — the sleeping setup, the kitchen, the power system, the water system — and how we used it across three national park trips.

The Full Build Walkthrough #

The video covers every system in detail. The sections below go through each one in writing for reference.

Sleeping Setup #

The third-row seat comes out completely (Honda makes this easy — the Odyssey’s Magic Seat system is designed for exactly this). The second-row seats also come out to create a fully flat floor.

A wooden platform spans the full rear of the van. The main sleeping surface is nearly full-size — wide enough for two adults lying side by side with room to spare. A foam mattress goes on top. On the passenger side, a second raised platform extends from the sliding door area and tucks under the main bed level, giving the kids their own sleeping zone accessible directly from the sliding door.

Privacy curtains hang on all the sliding door windows and the rear. Once the curtains are drawn the interior is completely blacked out — you sleep as well as you would in a tent, without the ground.

Under the platform there is significant storage: a floor hatch gives access to the space below where camping gear, bags, and supplies live.

Kitchen #

The kitchen is built into the rear of the van and deploys when you open the tailgate. It has everything you need to cook a real meal.

Counter and sink: A marble-look laminate countertop runs across the full rear width. A stainless steel sink sits on the left side, plumbed to the fresh water and grey water systems. There is enough counter space to prep food comfortably.

Induction cooktop: A full-size induction cooktop sits on a custom wooden pull-out unit on the passenger side. The unit slides out from under the counter and extends beyond the tailgate — so the cooktop is outside the van when in use, keeping heat and cooking smells out of the sleeping area. The wooden box has two drawers below for utensils, spices, and cooking supplies.

Coffee: A Keurig sits on the counter. Morning coffee at a national park campsite, no compromise.

The tailgate as a wind break: When the tailgate is open and the cooktop is extended, the tailgate itself acts as a partial wind and weather break for the cooking area. In practice this works well even in variable weather.

Power System #

200 Ah lithium battery bank charged by solar panels mounted on the roof rack. The solar setup keeps the battery topped up through normal driving days and sunny campsites — in practice we never ran low on power across any of the three trips.

A custom wood-mounted power panel is accessible from inside the van near the sleeping area. It has:

• Rocker switches for individual circuits
• Volt and amp display showing battery state
• USB-A and USB-C charging ports
• 12V outlets
• Shore power input for when you have hookups

The induction cooktop, the water pump, phone charging, and interior lighting all run off this system. With 200 Ah you have more than enough capacity for a family for multiple days between solar recharges.

Water System #

Fresh water: A blue jerry can lives under the sink inside the van. A small 12V pump pulls water from the can to the sink faucet — proper running water for dishwashing and handwashing.

Grey water: A separate container collects drain water from the sink. You empty it at campground dump stations or designated grey water disposal points.

The system is simple, lightweight, and completely self-contained. No hookups needed.

Roof Storage #

A large cargo box sits on the roof rack alongside the solar panels. This is where bulky camping gear lives — sleeping bags, extra bedding, hiking gear, the kids’ gear. Keeping it on the roof frees up the interior and the under-bed storage for kitchen supplies and daily-use items.

Camp Mode Setup #

Pull into a campsite, open the tailgate, and the van goes from road mode to camp mode in about 15–20 minutes:

1. Open tailgate, slide out the cooktop extension unit
2. Pull out the foam mattresses from under the rear hatch storage
3. Lay mattresses on the sleeping platforms
4. Hang privacy curtains on sliding door windows
5. Set up the fresh water can and check the pump
6. Lay out a ground mat outside the sliding door

That’s it. The kitchen is already built in — nothing to set up there. By the time the kids are out of their car seats, camp is ready.

The Trips #

Glacier National Park #

Our first real outing in the converted van. Going-to-the-Sun Road in a minivan campervan is a legitimate way to see Glacier. We camped inside the park, woke up to mountain views, and cooked breakfast at the tailgate every morning. The kids thought sleeping in the van was the best part.

Banff National Park #

Banff required crossing into Canada, which means the van needed to be tidy and the water system properly accounted for at the border. No issues. The Icefields Parkway is one of the best drives in North America and doing it in your own kitchen-equipped campervan — stopping where you want, eating when you want — is the right way to experience it.

Yellowstone National Park #

Yellowstone campsites fill up fast. Having a self-contained setup meant we weren’t dependent on sites with hookups — we could take any site that was available. The induction cooktop and full battery system meant we cooked every meal without needing any campground facilities beyond a fire ring.

What Worked #

The minivan format. A lot of van conversion content defaults to full-size cargo vans. The Odyssey was the right call for a family with young kids — it’s easier to drive, fits anywhere, and the sliding doors make the kitchen setup genuinely pleasant to use.

Induction over propane. No propane tank, no gas smell, no open flame. The induction cooktop runs off the battery system and works as well as a kitchen stove. This was one of the best decisions in the build.

Under-bed storage. The floor hatch and the under-platform storage space is where the build really earns its keep. Everything has a place and nothing is piled on the sleeping surface.

Privacy curtains. Simple and cheap, but they transform the sleeping experience. The van feels like a real sleeping space, not a vehicle you’re camping in.

What I Would Do Differently #

Better cable management in the power panel area. Functional, but not clean. I would route cables more carefully from the start rather than cleaning up after the fact.

A dedicated spot for the water cans. The fresh water can lives under the sink but isn’t secured. On long drives it shifts. A proper mount would fix this.

More counter workspace. The kitchen works well but counter space is always the constraint. A fold-out side table off the sliding door would add useful prep space.

Is It Worth It? #

For a family with young kids: yes, without question. Three national park trips that would have cost thousands in hotels cost us campsite fees and groceries. The kids remember sleeping in the van as vividly as they remember the parks themselves. And the build — done once — is ready to go every summer with almost no setup.

The Odyssey is back to normal daily driver configuration now. The platform, the kitchen unit, and the power system are all removable. That reversibility was intentional: the van needed to work as a school-run car in September and a Yellowstone campervan in August.

It did both.
