The price stays the same for you, so nothing extra to pay. It does not change what we think of the filters either: they have been fitted in our own van for years.

We bought Humbär and built him out for one reason: vanlife. He was going to be our home base for the next few years, so we gave up our apartment to live and work from the road as digital nomads. That means Humbär was built from day one to be a long-term hideaway out in nature: off-grid and comfortable, but easy on the eyes too. And we wanted to build him out as cheaply as possible, without cutting corners on anything that truly makes everyday van life cozy. If you're thinking about converting a vintage van for vanlife yourself, this post might give you a better sense of what to expect financially. For us, the total came to CHF 24,836.08.

What kind of vintage van did you get?

Humbär, a first-generation 1992 VW LT 35

Humbär, our base vehicle, is a 1992 VW LT 35: a panel van with a fiberglass high roof, in the shorter of the two versions. In today's sizing lingo that makes him an L2H2, 15.9 ft (4.855 m) long, 8.4 ft (2.57 m) tall and 6.7 ft (2.04 m) wide, with a cargo floor of 9.7 ft (2.97 m).

Under the hood hums a 2.4-liter six-cylinder gas engine with 70 kW (94 hp). Humbär already came with power steering and a catalytic converter, which makes him one of the youngest of his kind.

We had our eye on the Mercedes-Benz T1 too. But the LT won us over fast, because it's a good bit wider. That meant we could fit the bed crosswise, and Frank, at 5'11" (1.80 m), fits in perfectly. Give or take a bad hair day.

How much did the van itself cost?

Van shopping: the day we bought Humbär

CHF 3,500, which borders on a small miracle. Humbär had about 75,000 miles (120,000 km) on the clock and was in good mechanical shape. Even so, he needed a bit of welding and some gearbox work right after we bought him. We had that done for around CHF 1,600.

That low price was only the opening act. With a vehicle more than 30 years old, don't kid yourself that handing over the cash is the end of the story.

What did the rust repair on the VW LT 35 cost?

Under the diamond-plate floor: two massive rust holes

Old vans and rust go together like peanut butter and jelly. Once we'd emptied Humbär out and pulled up the diamond-plate floor, we got the scare of our lives: two big rust holes. On top of that came a classic weak spot of the first-generation LT, rust along the windshield. So off to the shop he went.

The rust repair set us back a hefty CHF 4,862.85. It stung, but it had to happen. Without a solid base, no build is worth the effort. Add roughly CHF 290 on top for paint, rust converter and sanding supplies.

Later on we had Humbär repainted in Greece, with more restoration and rust work thrown in, at a price we thought was more than fair.

How long did the build take, and what did it cost?

Under "Construction" (CHF 252.41) we logged tools and small stuff like Sikaflex and saw blades.

Even mid-build we took Humbär out to play. Right after the vinyl floor went in, we drove up to Sweden for the summer

Honest answer: you're never really done. Our six-month plan quietly snowballed into 18. At some point we just said it out loud: we hit the road now, or we never will.

We both had full-time jobs. During the week Humbär lived in a covered hall, and on weekends we drove out to Evelyne's parents' place and built in their parking lot. Saturdays were for sanding, sawing, figuring things out and runs to the hardware store. Sundays, out of respect for the neighbors, were for the quiet stuff, like painting and fitting things in.

From picking Humbär up in early February to the end of 2024 alone, that's 48 weekends. At about eight hours a day, it adds up to a good 750 hours each, or more than 1,500 hours between the two of us.

Before we started, we did some napkin math: if Humbär came in under CHF 30,000 with the build included, we'd call it a win, even with our special requests like the wood stove. In the end, the van, the first round of repairs and the entire interior and exterior build came to CHF 24,836.08. Mission accomplished!

How much did you spend on insulation, flooring and furniture?

More than we bargained for! The interior category added up to CHF 6,301.78 in total. Leave out the wood stove (CHF 1,438) and the fridge (CHF 338.40) and you're still looking at around CHF 4,525 for insulation, flooring, lumber, furniture and the kitchen.

Lumber in particular is pricey in Switzerland. During the build we rarely walked out of Hornbach, our trusty hardware store, for less than CHF 100.

Insulation: We went with 6 and 19 mm Armaflex, about 27 m² of it, and wrapped the frame members and crossbeams in felt on top.

Floor: Wooden battens with insulation in between make the base, topped with OSB boards and a glued-down vinyl floor. That's the one thing we'd do differently today: OSB is pretty flimsy, and something sturdier would have been worth the extra cash.

Walls: Plywood all around, with every cable tucked out of sight behind it. For a little flair, we treated ourselves to Swedish wallpaper.

Kitchen: Fun fact, nothing in here is made for camping. The sink, faucet and induction cooktop are regular household gear, plenty of it from IKEA. The one exception is our dual-zone cooler, which is built for life on the road and sits on a heavy-duty slide rail.

What did the windows, roof fan and roof rack cost?

We broke through! This is where the MaxxFan goes

To make the inside feel homey and flooded with light, we put in a big skylight plus a window right where our dining table sits. Above the kitchen sits the crowd-favorite Maxxfan, which can pull fresh air in or push stale air out.

Up top, Humbär got a roof rack: eight crossbars tied together with aluminum profiles, which is where our four solar panels live. Later on we treated him to a Fiamma bike rack too. All in, the exterior came to CHF 2,118.03.

What does it cost to build an off-grid camper with solar and a lithium battery?

Our goal was to camp out in the wild for long stretches, fully self-sufficient. So we planned in a 5 kWh lithium battery, 500 Wp of solar on the roof and a beefy inverter. Curious how the system is holding up after a year and a half on the road? We dig into that in this post.

After the interior, the electrics are the biggest line item of the whole build. All in, we put CHF 3,921.88 into our electrical system. Here's where the money went:

Electrics by component, in CHF
  • Solar4 x Wattstunde WS125SPS-HV panels, Victron MPPT 100/20 charge controller, MC4 connectors910.77
  • ChargersVictron Orion-Tr Smart 12/24-15 (DC-DC, while driving), Victron Blue Smart IP22 24V (shore power)348.22

  • Outlets and switchesInprojal System 10.000, 6 outlets, switches and frames206.37

The big battery lets us cook without gas, and the solar keeps us independent out there. That doesn't mean the sun always delivers, though. In winter and during long gray spells we have to keep an eye on what we use, or plug into shore power.

The upside: we don't spend a single franc on gas. Since we cook exclusively on induction, we never have to refill or swap gas bottles on the road, which adds up fast, and there's no gas inspection to pay for either.

What kind of water system do you have in the camper, and what does it cost?

Before we built a thing, we thought long and hard about how big our water system should be. We wanted it easy: no plastic bottles and no hauling jerry cans around. So we mounted an 84-liter (22-gallon) fresh water tank and a 54-liter (14-gallon) gray water tank under the floor. The gray water tank alone, mounting kit included, ran CHF 226.15.

We skipped a shower, because all that moisture inside felt too risky to us. There's no hot water either: way too much energy for way too much complexity.

The water system cost us about CHF 946. If you'd like to build your own, our detailed parts list is in this post.

Water quality is the one place we refused to cut corners. We wanted the cleanest, safest water we could get on the road, so we put our money into the best filter system out there from day one.

What kind of toilet do you have in the van, and what did it cost?

A toilet on board was non-negotiable for us. If you love camping off the beaten path, we think it really matters not to leave your, ahem, souvenirs out in nature. It's nicer for everyone, and it helps keep those places beautiful for the long haul.

We went with a urine-diverting dry toilet from the Swiss company Flower Pott, the Bonsai model, free of chemicals and free of plastic, for CHF 1,050. With two of us on board, we empty the urine tank about every three days. The solids land in sawdust, get churned by an electric crank every four hours, and after two weeks they can go in the trash or on the compost.

Where did you save the most money on the build?

Here's the big one: you are not the only person building out a van right now! Plenty of people who've wrapped up their build sell the leftovers on tutti.ch, basically Switzerland's Craigslist (in Germany, try Kleinanzeigen). The stuff is often brand new and still up to half off the store price. That's how we scored 8 m² of Armaflex insulation for CHF 115, butyl sound deadening for CHF 30 and even our fresh water tank: CHF 40 instead of CHF 140.

We even found tools on tutti, like a jigsaw for CHF 20 and a drill for CHF 50. Practically a steal!

What was truly worth the money?

Our wood stove is gorgeous, but let's be real, it wasn't exactly the most sensible investment. For those CHF 1,438 we could just as well have put in a diesel parking heater. It probably would have been more practical and spared us a fair bit of work. But as so often with our old Humbär, heart wins over head.

What we'd throw money at again any day is a powerful electrical system (CHF 3,921.88). Being able to run the coffee machine, the oven or the kettle without doing power math every single time makes van life almost as comfy as living in an apartment.

The insulation, about CHF 550 worth of Armaflex and butyl, was worth every last cent too. Even on cold nights, Humbär holds on to the heat amazingly well. When we fire up the wood stove in the evening, it often stays toasty until two or three in the morning, which is plenty of time for us to be sound asleep.

Does a DIY build pay off compared to buying a ready-made camper?

For us, building it ourselves paid off. We know every single screw, and Humbär turned out exactly the way we pictured him. Wherever something really mattered to us, we got to decide where the money went.

Evelyne designed the entire interior on paper first, then brought it to life in the van, just the way we'd pictured it

Whether a DIY build is cheaper than a used camper in general is hard to say, though. Factor in the tools, a place to build and all those hours, and you might land on a different answer. A ready-made camper can be just as well equipped, or better. Just not necessarily the way we'd want it. In the end, though, it was never really about the money or the time. It was about building a camper that feels like home and reflects who we are in the most beautiful way.

And then there's everything we learned in a year and a half of building. That part is priceless.

What do you regret about Humbär?

About the build? Hardly anything! We're so glad for every minute we poured into Humbär. All those big and little decisions pay off every single day on the road, from the well-thought-out water system to the outlets sitting exactly where you need them.

That said, we'd be lying if we told you Humbär is perfect.

The thing that genuinely bugs us a little is the height of the windows. With the high roof we stand pretty tall in there, while the windows still sit at their original height. Translation: if you want to soak up the view, you have to duck down first. The rear windows sit so low, too, that from inside we barely catch a glimpse of the scenery. Luckily there's an easy fix: fling open the back doors!

Would we convert an old van into a camper again?

Funny enough, every now and then we catch ourselves wondering whether we'd go through that year and a half of building Humbär all over again.

Because we have to come clean about one thing: Humbär isn't exactly the most rational way to get from A to B. He's old, not what you'd call thrifty, and about every six months he needs a solid dose of TLC. In return, this old van has taught us an incredible amount. Woodworking, electrics, fighting rust: all skills that will come in handy one day when we fix up a house of our own.

And today, when we swing open the back doors somewhere with a killer view, brew some coffee and have breakfast, we're grateful for every hour at the hardware store and every tiny detail we put in back then.

Like we said, Humbär isn't perfect. We know pretty much exactly where we simply ran out of steam and decided: that's it, we're hitting the road. But somehow that's part of him too. For now, anyway, we're pretty happy to spend our weekends traveling and soaking it all in instead of sawing, sanding and driving screws.

So, would we build out a van again? Tough one. Life is short, and there are so many wonderful things you can do with your time. In another timeline we might have spent that year and a half working in Yosemite, backpacking through Southeast Asia and Australia, or building a tiny house in an enchanted Swedish forest and opening a little bakery there. Every one of those sounds at least as lovely.

But in this timeline, we poured our time, our energy and a whole lot of love into Humbär. And now we get to roam all the places with him that we dreamed about while we were building.

So would we do it again? No clue. But we wouldn't trade Humbär for anything.
