Van Conversion Build Journal: How We Built Our Campervan

Van Conversion Build Journal: How We Built Our Campervan

Tempted by Vanlife? Looking for how to convert a van to a campervan? We obsessively documented EVERYTHING from our DIY campervan conversion process: how to's, products and material, tools, lessons learned, etc. Whether you are converting a Ford Transit, a Mercedes Sprinter or a Ram ProMaster, it's all good: our step-by-step directions should point you in the right path whatever the van you choose to convert. Happy campervan conversion!

In each GUIDE of this Build Journal, you'll find:

How To's
Step-by-step, illustrated, and explained.
Products and Material
Why we chose them. How we installed them.
Nothing fancy. Just common handyman tools.
Second Thoughts
If we had to start over, what would we do differently?

There are 3 options to find your way around here:





Our Build Journal below is presented chronologically. That being said, the order of some steps can be interchanged; for example, you could decide to upgrade the tires, the radio, or to install the Air Lift system at any moment. But some steps should be performed in the right order... To clarify the timeline below indicate, what we think, is the critical path:



First things first. We’re not off road enthusiasts, but we’re not roadies either. We need tires that can handle highway, off-road and snow as well. And we don’t mind the badass look too, because we’re such badass people. Whether you are converting a campervan or own a work van, this is something to consider.





2- Maxxfan Installation

Do you have what it takes to convert a brand new van? This is the test right here. We just brought home a new shiny van and we're about to cut a big hole through the roof to install a fan... THERE IS NO TURNING BACK NOW!

3- Window Installation

We did NOT add a window above our bed and, well, maybe we should have... We're considering adding one to our van during summer 2019 (edit: we didn't! 2020 maybe?). If we had to start over we would most likely do it at this point of the conversion, right after the Maxxfan installation.

4- Solar Panels Install

Off-the-grid or not, we still have to run the fridge, the fans, the water pump, the lights, etc; our autonomy and freedom depend A LOT on electrical power at all time. Harvesting power from the sun feels a bit like cheating to us: we LOVE IT! If you say freedom, we say solar!

5- Passenger Swivel

We chose to convert the largest Ford Transit available, thinking we would have plenty of extra space... Note by us from the future: "nope, no extra space"! Indeed, every precaution should be taker to maximize the space available. Adding swivel seats is one of these precaution, we HIGHLY recommend it! We use it constantly. So let's get to work!

6- Driver Swivel

The driver swivel seat installation requires to lower the e-brake, so it's a bit more complicated than the passenger seat. But in retrospective, it's essential for our layout: we use it everyday. So we're glad we went for it!




7- Fiamma Awning

If space is a rare & precious thing in a van, why not create some space outside? An awning is not cheap, but we'd rather be outside. Rain or shine. Do we actually use it? Please take the time to read our "Second Thoughts" in this article...

8- Webasto Heater

If you have enough budget to invest in a van, ski gear and ski passes, then you have enough budget to invest in a dry heat source; we can’t recommend that enough. We LOVE our Webasto as it has "unlimited" heat source (it uses fuel from the van's tank, so no need to refill a propane tank), it keeps the humidity level below 40% (even when drying ski gear!) and it's powerful enough to keep the van warm (68F) at all time. This thing is awesome.





9- Propex Heater

Webasto AND Propex, do we really need both? Here's the situation: right before our first winter (2017) we had some issues with the Webasto. So we decided to add the Propex as a backup heat source, because being parked at -22F (-30C) is not a joke; having heat is safety matter! Turns out our Webasto is working fine, so we didn't really needed the Propex after all, but it's nice to know we can have heat when we forget to add enough gas in the tank AND a second heater is not a bad thing when temperatures drop below -20F (-30C)...




We don’t like drilling holes in our van as it could: attract rust on bare edges, spread metal chips all over (almost impossible to remove and will attract rust), interfere with your van electronics (!). Cross Nuts are the solution! We prepared a fully detailed article about Cross Nut (choosing the right size for your van, installation tips, etc). Check it out!

10- Floor Installation

And now is the time to install a floor in our van because, you know, we need something to walk on! That’s being said, a floor has many other primordial functions than just supporting our feet. Indeed, a proper floor installation prevents water infiltration (= rust), provides thermal and noise insulation, and serves as anchor for the cabinets. In addition it should be resistant to wear, be able to withstand enough weight, not produce any squeak, and … look good (yep, that counts!).

11- Thinsulate Insulation

Welcome to the most controversial topic on van conversion: Thermal Insulation! One could spend days reading about it online, only to find out there is no consensus on that topic... Our researches on insulation and condensation led us to choose Thinsulate and we're glad we did! After two winters chasing snow full time, Thinsulate kept us warm even down below -22F! And it still looks great after all this time (no molds, no bugs). Awesome!

12- Platform Bed

There are a lot of creative way to make a bed: Murphy bed, pull-out slats, futon, etc. We personally wanted a permanent bed (so we don't have to do/undo the setup everyday) and to leave plenty of room for the "garage". A raised platform bed seemed ideal and we don't look back!

13- Slide-Out Bike Rack

We won’t lie, this whole FarOutThing revolves a lot around the mountain bikes. They deserve a neat and functional storage. And we can't emphasis on that enough: repetitive tasks should be make easy (we ride almost everyday in summer, so that's definitely a repetitive task)!

14- Fridge & Electrical Cabinet

It's the first cabinet we're building, so it's quite the learning curve... but we made it! In retrospect, we're VERY happy with the large countertop (we cook a lot in the van) and we like that the electrical system doesn't use much room (but it's challenging to work in it because it's so small).




15- Electrical System Guide

Designing a 12V electrical system from scratch is not a simple task, we learnt that the hard way. It is where most people get discouraged, so it's BY FAR our most detailed guide on this website. You'll learn how to size your components, decide between different technologies, make the connections, where to install fuses and breakers, etc. We're also sharing our Wiring Diagram, which is flexible and can be implemented on pretty much anything (Transit, Sprinter, ProMaster, Tiny House, Boat, Trailer, etc!). Hope that helps!

16- Overhead Storage

There's not much use to make of the space above the countertop... except, of course, adding storage! The overhead storage will be used to put away our kitchen stuff (dishes, pots & pans, food containers, espresso machine, etc).

17- Bedroom Storage

In small space, organization is the key to sanity! Looking back, we LOVE our bedroom storage because we both have our own "storage cubes" to put away our stuff, organized by categories. No random packing, it's all neat!

18- Sink & Stove Cabinet

Adding a propane range and pressurized water was a GREAT decision, considering we live full time in the van. The sink & stove cabinet is home to the Atwood range, the Dometic sink and has some storage for household products & food as well.

19- Water System

We hesitated to install a draft beer system in our DIY campervan conversion, but we finally installed a pressurized water system instead. This is the Water System Installation of our DIY campervan conversion. Materials, tools, cost and installation. Fully illustrated to make it easy to understand!

20- EZ-COOL Insulation

We chose Thinsulate (and we're glad we did) as our “main” thermal and noise insulation. To be effective, Thinsulate requires to be fully expanded: that’s almost 2 inches thick for SM600L Thinsulate. There are locations where we just don’t have that space (we'd rather keep that space as living area), so we installed EZ Cool to act as thermal break.

21- Wood Paneling

Right from the start, we knew we wanted a rustic finish. It is fairly easy to obtain a nice & clean finish with the tongue and groove paneling: each plank will sit flush the the adjacent planks, creating a uniform & continuous surface. The planks are relatively thin at 5/16” thickness, making them flexible enough to conform to the van funky surfaces. We did not sand the planks, but we finished them with varnish to protect them against a spaghetti incident.

22- Foam Blobs Makeover

The foam blobs... we don't really like them, but we can't really get rid of them either (because of the adjacent air bags). So we did our best to make them look good. Check it out!

23- LED Ceiling Lights

After a few trial-and-error we finally found what (we think) are the perfect recessed ceiling LED lights! The first LED we ordered were WAY too bright as the glass was clear instead of frosted. Even with a dimmer, the light was shocking for the eye. Then we stumbled on the Acegoo LED lights…

24- Nature's Head Composting Toilet

We plan on living full time for a year in the van (update from the future: we're currently in our third year!). For a minimum of comfort (and convenience), we really wanted a toilet and after reading about composting toilets, it seamed like the perfect solution for us! It’s honestly really easy to install and manage; there is no odor (that’s right!) and no black water to deal with. It's one of these thing we couldn't live without. Sweeeeet!



25- Propane System

Propane stores a LOT of energy in a compact and cheap way. To get an equivalent amount of energy via solar & batteries would cost thousands and thousands of dollars. To make it perfectly safe, we enclosed our propane tank in a sealed & vented locker. This Propane System Guide has everything you need to build your knowledge and execute your build. We even share our Propane Diagram in there, hope that helps!



26- Upfitter Auxiliary Switches

The Ford Transit can be ordered with the optional Upfitter Auxiliary Switches, but getting access to their output is a bit tricky. Fortunately, we made our homework and we’re guiding you through the process!

27- Air Lift Spring Kit

As we progressed in our conversion, the van got heavier and we could see the back starting to sag... We decided to add an Air Lift Spring Kit to bring the van back to it's original level and to improve the ride. And with the on-board compressor and the wireless remote, we can adjust the air pressure in the springs on the fly to level the van for the night! Neat!

28- Mosquito Screens

And here’s the only non-DIY part of our Transit van conversion: the mosquito screens. They’re almost too good to be true, there is NO WAY we could have match the functionality or quality of those. So we did not bother making them!

29- Radio Upgrade

The Ford Transit can be upgraded with an aftermarket radio and we’ll show you how in the following article. We went from the basic Ford factory AM/FM radio to the Pioneer AVH-W4500NEX 6.94″ TouchScreen Multimedia Receiver: it has Android Auto & Apple CarPlay (wireless or USB), backup camera ready, DVD receiver, Bluetooth, SiriuxXM, etc. Sweet upgrade. Let’s get to work and get done with the installation!

30- Speakers Upgrade

After upgrading our radio unit, the next smart move was to upgrade our speakers. We ordered our Transit with the basic factory radio which includes 1 speaker in each front door; and they’re not that great… we’re not audiophile or something; in fact we’ve been using the same small portable stereo in our house for the last 10 years, but we quickly got bored of the flat sound of the Transit’s factory speakers.

31- Adding Speakers To The Headliner

Let’s recap: in our quest for the perfect sound, we upgraded the Ford Transit factory radio to a Pioneer AVH-W4500NEX AND we upgraded the factory front speakers. It definitely improved the sound and we were pleased with the results. We enjoyed that setup for two years, but then we couldn’t help but push our quest even further: how can we make the audio even better? Indeed, because the front speakers are located in the doors close to floor-level, the sound quality was not as good under loud ambiant noise (driving under heavy rain or wind, or when cooking in the van). So here we are today, adding Rockford Fosgate speakers to the headliner; and this, my friends, complete our quest for the perfect audio experience. It’s exactly what we were looking for!

32- Exterior Shower

We LOVE riding our mountain bikes. It can only means two things: 1-We drink a lot of craft beer 2-We take a lot of showers. Let’s focus on item #2 in here. This is our van conversion exterior shower setup.



33- Insulated Window Covers

While curtains work for houses, we think insulated window covers are better for campervans. They are lightproof (for shade & privacy) and insulated (to keep us cool in summer, warm in winter). We’re obsessed with functionality and with the rare earth magnets all around the edges, they just “snap” to the van metal window contour. Easy breazy! Similar design should work for Transit, Sprinter or ProMaster.

34- Rear Floor Vent

We are adding a second floor vent to cool down our bedroom (and the whole van too)! It’s similar to the fridge vent except that we added a gate, an inline fan and a duct to route the air above the bed.

35- On-Board Tire Inflator

We previously installed an Air Lift Kit and we're about to tap into it to solve a third-world problem: adding air to our mountain bike tires without a floor pump. It's not by any mean an essential upgrade, but we do actually like it a lot!

36- The Garage

La Pièce de Résistance. All this van conversion must serves our end goal: RIDE MORE. That means we're packing a lot of gear and we want to be able to load / unload it easily. If we have to play Tetris each time we need to access something, it isn't gonna work in the long term; we can do better than this. So here it is: The Garage!

37- Bike Repair Stand

We're pretty obsessed with our bikes and riding (almost) everyday means a LOT of maintenance and repairs. For the last two years we improvised repair stands with picnic tables, Adirondack chairs, bike racks, and other unrelated objects that are definitely not suited for the job. A repair stand is not absolutely necessary, but it makes mechanical sessions much more efficient and enjoyable! After holding back on this upgrade for the last two years, the time has come 🙂

38- Dash Cam

People elect to install dash cams for several reasons: evidence in case of accident, prevent fraud, capture footage of a road trip, etc. In the article below, we documented how we installed the Garmin Dash Cam Mini in our Ford Transit and why we chose it. Hope that helps!

39- Add & Program New Keypad

The Ford Keyless Entry Keypad allows to unlock your vehicle, you guessed it, without using your keys. Turns out we use it a lot when going for a bike ride or skiing, because we like to pack light and getting stabbed by your keys when crashing is no fun. We’re no beach bums, but we heard surfers love it as well! It’s possible to order the Keyless Entry Keypad with a new vehicle, or to add one (or up to 8) later. After using the keypad on our Ford Transit for two years, we’re adding a second one on the passenger-side for more convenience. Here is how to install and program it!

about us

Nice To Meet You.

Hello! We’re Isabelle and Antoine 🙂 In 2017 we sold our house (and everything in it), quit our engineering careers and moved into our self built campervan. We’ve been on the road since then and every day is an opportunity for a new adventure; we’re chasing our dreams and hopefully it inspires others to do the same!

45 thoughts on “Van Conversion Build Journal: How We Built Our Campervan”

  1. One quick questions as well. I noticed you went with factory installed side windows. Did you ever consider installing aftermarket at any point in order to have windows that opened up in some capacity? Do you ever wish you windows were able to open for airflow?

  2. This is the most unbelievable build site I have ever come across. My wife and I are 1 year out from leaving our jobs and starting on a journey incredibly similar to yours (currently in the sell everything phase). We are both mountain bikers and skiers and plan to live life as the two of you have. I had a very similar build in mind and this build guide is exactly what I have been looking for! Thank you so much for putting all of this together (I will certainly be clicking on affiliated links). Hope to see you out on the road some day!

  3. Hi!
    Any suggestions on what to do with the rear doors and Passenger side sliding cargo door. I have them insulated and need a solution to covering them. I have the same year and model as your transit.
    I’ve followed you on all the insulation, plank paneling for the walls and ceilings, Floors, etc…
    Thank you so much! youre website has been a tremendous help 🙂

  4. Hi, thanks for the amazing information and details, I’ll be using your site (and links for purchases) as we start our conversion. What is your opinion on getting a van with packages/options vs after market products, this would be for things like swivel seats, navigation system, premium sound, etc.?

    • I’d say it’s case-by-case evaluation… The swivel are new for 2020, no one has feedback at the time of writing these lines. The “deluxe” Ford radio is quite expensive, so we preferred an aftermarket one. If you can get factory speaker all around, i’d say go for it.

      Bottom work: It really is case-by-case. Read the reviews, check the specifications, compare the price; then it’s possible to take a decision.

      Happy new year!

  5. Hello Antoine & Isabelle,

    First of all, thank you so much for providing all of this priceless information. It has made planning SO much easier for my girlfriend and I as we start the build process. We are making sure we buy as many products through your links as possible. Question: I noticed in your build sequence that you installed the insulation before the electrical system. Would it be a terrible idea to reverse that order? (i.e. do the electrical system first). Thanks!


    • I highly recommend insulating first, then route the wires. If anything happen (bad connection, modifications, add more wires, etc) it is then accessible. Also having the wires on the “hot” side will minimize condensation on them if you use the van in cold weather.

      Good luck!

  6. Hey Antoine
    Did you guys have to custom order your Transit? I’m having trouble finding new transits in my area that are equipped with the heavy duty alternator and dual batteries. Do you think this would be more trouble than it’s worth to install after market or should I just be patient and order my van? If you did order how long did it take before you were able to drive it away? I was told 10-18 weeks! Thanks guys.

    • It seems Transit sold of the lots don’t have no options at all, so we did a custom order. It took about 4 months to arrive…

      Don’t know about aftermarket installation. What about cruise control?

  7. Hey Guys, been spending some time studying your electrical (we have the 2018 largest Transit). So far, learned a ton but still have more things to study up on. A question for you: Any particular reason you went with a separate inverter and charger as opposed to one unit that combines both? Per your recommend, we’ll be going with Battle Born (2 batteries) and a 2000W inverter/charger – to be able to use a 4 gallon electric water heater that needs 1400W. Should there be any concern putting the batteries in the “garage” area and running wires from under-the-seat van battery to a B2B charger and then to the batteries in the back? Any comments/help will be appreciated. And we’re definitely going to buy your diagram once things make more sense! Thanks!
    Slav & Heather

  8. Hey, building my van and been following you guys for a bit now. What type of wood did you use for your vertical beams on walls and ceiling? Would you recomend using the same? Also are these weight supporting anything or did you only crossnut to frame?

  9. Hello! I’m interested in how/why you made the decision for the 250 over the 350 besides cost of course? Do you know how much margin you have on weight capacity? Have you weighed the final build fully loaded?

  10. This is the most thorough build description I’ve seen! Great job! We get quite a few inquiries from our customers and I’ll make sure to send them here.

  11. Hey far out ride, great info, I purchased the wiring diagram and have been going through it, 1 question, with the shunt which side connects to the negative bus bar the 50mv or 500a side, and then the other side connect to the neg terminal of house battery, is this correct, thanks

  12. Thanks for your van build journal! It has helped us immensely and we’ve used your links whenever applicable.
    One more question, could you tell us which curtain rod you used?

  13. Thanks for sharing so much detail on your build. It has been great inspiration for our upcoming build. We are looking to purchase a 2018 Transit 250 High Roof with 3.31 limited slip differential and we aren’t sure which length we should get. Do you ever feel like the extended transit is too long? I understand that parking will be tougher and that is one downside, but are there any other downsides you can think of for having the longer version? Do you ever feel like it is hard to maneuver? We will end up driving ours through cities at times and will also be in a lot of National Parks Camping. Did you even take the shorter high roof version into consideration or were you always set on the extended version?

    • For full time living, we think the extended length is the way to go. But then we have our bikes inside, an oven, toilet, sink, fridge and a lot of gear…

      It’s not too hard to maneuver; you quickly get used to it. One downside is the long overhand behind the rear wheels: on off roads where there are steep departure angles, it can touch the ground.

      If you spend a lot of time in the cities, of course the shorter one would make it easier to park… we normally avoid cities so it’s not an issue for us.

      Sorry, we’re not really helping here, but it’s a very personal decision! It depends a lot what you plan on doing with the van!

      Good luck!

  14. Wonderful, informative site you have here! Which makes me wonder, how did you come up with all tje info you needed to put all of this together? What were your main information resources? Certain blogs, websites, or books? I want together supplement all the great stuff I’m learning from you, thanks!

  15. Hello,

    Thank you for your website… it has been very helpful during our van conversion. I noticed you guys are up in WA… looks like you are close to us. If you need a place to park you van for a few days we are located in East Wenatchee. We have a great ski resort (Mission Ridge) less than 30 mins from our house.
    I am interested in your lift hit you put on the van… I am assuming you ran into problems when trying to go off road? Does it really give you 3 extra inches of clearance?


    • Hi and thanks for the invitation 🙂

      The long overhang behind the rear wheels of the Extended-length Transit are a limiting factor. The lift kit raise the BACK OF THE VAN 3 inches (not the entire van), so that helps with steep departure angle. It also helps handling.

      Have a good one!

  16. amazing as far as I can see, swivel seats are genius. one thing stuck out though, about the bike tyre inflation..i get your jokes all through the site but inflating with a track pump is dangerous? hmm..should I trust you guys ‘coz that’s one thing that is cray cray

  17. I would first like to say awesome website! The layout and how helpful everything is makes this a go to site. With that being said I was wondering what everyone thinks about tire choices. The stock tire on a Ford Transit is the Dynapro HT 235/65r16 LR C its max load is about 3200lbs, while the BFG KO2 (amazing tire by the way) 225/75r16 LR E has a max load of only 2700lbs even with it being a 10ply tire. So that ends up being a difference of 500lbs a tire. I’m not saying the KO2 can’t handle the GVWR of 9000lbs, but if you start throwing in pulling a trailer you can quickly go over the max of the tire.

    • Good point: if you plan on max out the payload on your Transit AND pull a trailer as well, choosing tires with higher load is probably a good idea. In our case, we don’t have a trailer so we’re good 🙂
      Thanks for your input!

      Good day!

    • Hi Robert,
      just went through your website.

      I must say that i really like your design! It’s clean and the colors give a nice touch!

      How does it feel to know that your almost done??

  18. Hi guys – steve from UK here, when I used to fit eberspacher(and we auto and bit if mikuni) professionally there are certain points I would note – thought perhaps I share them with you. The designs pecs – wiring etc were slightly different over here – we dealt with eberspacher direct and not espar which if h re all looked after the franchise hire over there. It seems to me couple of things ga you may have missed-so here goes – no offence intended. When you drop down the fuel rank – I found minimal is best don’t drop down more than you gave to. I sent your hole in the top where you propose to mount it – try and work out where the existing tank float is so as not to interfere with it. A point you missed-it with a hacksaw the standpipe you are inserting so it clears the bottom of the rank. The standard is to cut it at an angle (truncate) so it is easier for future to siphon out – of course clear off burs before you mount it. Make sure the inlet of the gas pipe clears they underside of the vehicle – all fuel runs gradual curves – nothing too tight. Another thing thar would be good would be to put in an emergency cut off in series to the fuel pump feed-this is a requirement in all UK psvs – good for private to in my opinion. See I g your pics I didn’t see evidence of small fuel clips that are prerequisite on the fuel Connections to make sure the unit is air tight. I could go in forever but just thought these few pointers. Espar o er there used to have download able I stalk manuals for us and Canadian regs. I used them couple of times as same over here we get charged for. Good luck and keep safe. STEVE Valentine Msaet. Airte, Amsterdam, Jib.
