DIY Micro-Camper – Living in my RAV4

RAV4 micro camper

I’ve always wanted to try out #vanlife, but I was not sure if I was ready to commit to the lifestyle, let alone purchasing and converting a van. I wanted to do a little test drive first, to see if it was possible to live out of my RAV4. I’m happy to report that the trip was a great success! Here is what I did to ‘convert’ my SUV into a micro-camper, and what I learned along the way.

My 2004 Toyota RAV4 and is pretty small. To give you an idea, it’s only about 5 inches longer than a 2020 Honda Fit (161 inches).  To be able to make living in this tiny SUV work, I needed to get a little creative. I broke the necessities down to four core functions and their requirements:

  1. Sleep: I must be able to lay completely flat (I’m about 5 feet 11 inches, or ~180 cm)
  2. Sink & Shower: I must have clean running water for at least 4 days.
  3. Kitchen & Food Storage: I must be able to store perishable food for at least 2 days, I must be able to boil water.
  4. Gear Storage & Lighting: I must be able to store all my camping/hiking/climbing/mountain biking gear. Lights must be dimmable, battery-powered, and can be attached to plastic surfaces. 

1) Sleep

To be able to live in my RAV4 means that I needed to sleep comfortably. This was my number one requirement. To accomplish this, I decided to build a sleeping platform for my RAV.  In the design phase, I was very ambitious and had grand ideas of all the features that I wanted it to have (slide-out table, flip-up storage compartments, shelves). When I got to the building phase, I realized that many of these features were not very practical, and simply not worth the effort.  I decided to focus on just the essentials, and that resulted in a much simpler, more versatile end product.

What I came up with for sleeping was essentially a table with an extension platform that folds out. The fully extended bed is 50 inches (127 cm) wide and 75 inches (190 cm)  long – just three inches narrower than a full size bed.

I purchased a 4 inch thick mattress tri-fold mattress (75 inches x 25 inches x 4 inches) from Amazon. This mattress is pretty comfortable, and it matches the length of the sleeping platform perfectly. When it is not being used, it can be folded and stored. If I am traveling with another person, I can buy another one to cover the entire sleeping platform. 

Waking up by Yellowstone lake on a chilly morning.
The load floor of the RAV4 is not even unfortunately, so I had to create custom supports that allowed the platform to be leveled.
I used these L brackets to make the platform more rigid and less squeaky. They worked very well and were relatively inexpensive.
Three hinges connect the fold out sleeping platform extension.
Waking up in the Mojave desert. It got hot real quick.

2) Sink & Shower

I bought a 7-gallon rigid water container from Amazon. This jug is great because it has a 7-gallon capacity, which lasts me about 5 days. It also has a spigot so I can control the flow of water coming out. When it’s full, the jug weighs about 60 pounds, so I decided to store it on the load floor so that it does not go flying around when I’m driving. I built my sleeping platform so that the support column can also prevent the water tank from moving around. I was able to use the uneven flooring to my advantage, using the raised surface to secure the tank between the passenger seat, support column, and the door.

To put this jug in ‘shower mode’, I had to hoist this beast to the roof of my car, and then stand under the spigot and pray that the water is semi-warm (see below). This is not a great way to shower. The water is oftentimes freezing, and it is not very efficient.

Using the jug as a faucet is much easier. Tip the jug over on its side and let gravity do the rest (see right). This is great for washing your hands and brushing your teeth.

Overall this solution worked okay, there are a few things that could significantly improve the showering experience which I will talk about in the “Lessons Learned” section.

3) Kitchen & Food Storage

Continuing with the theme of keeping things simple. For food storage, I purchased a Lifetime 28-quart cooler (after countless hours of research, coolers are serious business… Who knew?) along with three Cooler Shock re-freezable ice packs. This did the job well enough, the cooler was able to keep food cold for 2-4 days depending on the conditions. I’m glad I did not go with the 55-quart option, that would have been way too big for one person. It would have also taken up too much room in my small RAV. I was surprised at how heavy the cooler is fully loaded, something to keep in mind.

The meals weren't exactly five star but the views made up for it.

I forgot to bring my Coleman 2 burner camping stove. Luckily I had my small MSR backpacking stove & cookset. It turns out that this was all I needed for my trip. Meals typically consisted of a wrap with some hummus or potato salad, shredded cheese, sliced deli meat, and some salsa. Canned soups were great, sometimes I’d heat up a can of soup in my MSR pot and eat it with a few tortillas. One night I forgot my matches and ate a can of cold Chef Boyardee ravioli straight from the can. It wasn’t bad, everything tastes pretty good after 16 miles of hiking up and down a mountain!

4) Gear Storage & Lighting

I need room to store my climbing, mountain biking, and camping gear in my RAV. I put my gear in clear plastic bins so that I can easily identify what gear is in which box. I designed the sleeping platform so that the plastic bins can easily slide in and out from underneath. This design resulted in a lot of space for storage, however, it came at a cost of headroom. The height of the platform made it impossible for me to sit up fully, this made changing and even drinking water a creative exercise.

For lighting, I purchased these fantastic little LED lights. They are thin, dimmable, warm-white LED, and has 3M adhesive to stick to plastic surfaces on the inside of my RAV. These lights are also powered by 3 AAA batteries so I did not need to worry about an external power sources. The lights came in a pack of 3, I put one by the door that I climb in, and two in the rear. They performed very well, highly recommended.

The warm glow of these LED lights reek of luxury...

Lessons Learned:

Dispersed campground near Teton National Park. The campground is called "Shadow Mountain".
Pretty easy to find a place to camp in the desert!
  • Finding a place to sleep is not always straightforward – Good planning and prior research are recommended. I did not do any planning during my trip, I’ve slept behind a Sam’s Club, a parking lot next to a lake, a bunch of dispersed campgrounds (some better than others), and at various trailheads. Waking up to a semi-truck unloading or a park ranger knocking on your window is not fun, take the time to do some research, book actual campgrounds, and be prepared to have a ‘plan B’ if all the campgrounds are full. My recommendation is to look for dispersed campgrounds, and if you are really desperate, drive down a small side road until you see a decent spot to sleep. You do not want cars driving past you while you are trying to sleep. If all else fails, head to a Cabelas, Walmart, or Sam’s Club. https://freecampsites.net/ is a decent site for finding places to park your car and catch some sleep.
  • The temperature of your car will fluctuate wildly – I’ve gone to sleep at 10:00 PM when it was 75 F in my car and woke up shivering and seeing ice on the windshield. Be prepared for wild fluctuations in the temperature of your car. A lot of heat escapes through car windows, so one way to try and trap heat is to make insulated window covers for your vehicle.
  • Being able to sit up straight in your car is important – Not being able to sit up straight makes it difficult to do basic things like changing or taking a drink of water from my Nalgene bottle. It’s a trade-off with storage, consider this when you are designing your sleeping platform. 
  • A hotel ‘break’ is a good idea every now and then – You can fill up your cooler with ice from the ice machine, re-freeze ice packs, shower, wash your clothes, and catch up on some high quality sleep. 
  • Overhead storage – I’m going to make some nets that attach to the roof, this allows me to put stuff in like my chapstick, phone, keys, a knife so that it doesn’t roll off the side of my sleeping platform. 
  • Eye mask – Bring one. Your car has a lot of windows, you’ll want a nice eye mask to block out all the light so that you can nap peacefully.
  • Patagonia Capilene Cool Daily Hoodies are great – I hate sunscreen, this hoody is rated for 50+ UPF sun protection, it feels good on the skin, light-weight, drys quickly, feels cool, even when it’s super hot out. I also like to wear the hoody under my hat to prevent sunburn on my neck and ears. Well worth the 55$ price tag.
  • Fitted blackout window shades – This provides privacy and keeps the light out. I didn’t have these so  I resorted to hanging my shirts on the windows, not a good look.
  • Bug net for windows – If you want a well-ventilated sleeping space (you do, trust me), then you’ll want some bug nets. In most of the places I camped, mosquitos were out in force. You do not want mosquitos in your car while you are sleeping.
  • Thick car sleeping bag – I only brought my backpacking mummy bag, which was light and thin. It’s pretty cramped and cold. I recommend getting a thicker sleeping bag designed for car camping.
  • Pump shower – I found out about this after I got back from my trip. This would have been great, it weighs 2 gallons so it is not too heavy, and it comes with a showerhead. I’ll be getting this for my next trip.
This is *not* where you want to end up, in the back of a Sam's Club because you couldn't be bothered to do some research beforehand.

I hope this guide has been helpful to you. Living in a SUV is definitely do-able, you just gotta go in with the right mindset and a little bit of research and planning. There are lots of cool places to explore in the United States, and having the flexibility to travel and live in your car will make for some epic adventures.
