My 4×4 Mercedes Sprinter Van Conversion
If you’ve been following along on Instagram, you know that I recently moved full-time into a 4×4 Mercedes Sprinter Van. I bought the van as an empty cargo van with big plans to convert it into the ultimate tiny home on wheels.
When I was coming up with the concept for my Sprinter van conversion, I knew I wanted not just an adventure mobile to haul my gear, but a comfortable place to live and work. With this in mind, I had a few priorities when I was designing the van:
I wanted the van to feel open and airy maintaining the walkway to the back door.
I wanted the bed to run vertically down the van rather than across, so I would have more leg room while sleeping
I needed a table where I could sit and do my computer work
I needed ample storage space to store gear, clothes, food, and other neccesities for living on the road
I wanted a toilet and shower
I wanted a permanent galley and a sink to do dishes in
My conversion took four months later and during that time my Sprinter went turned from cargo van to a fully custom camper van.
Now that my custom Sprinter Van conversion is complete and I’m all settled in, I wanted to share the details of my buildout with you.
First, watch this video and get the full inside tour of my 4×4 Mercedes Sprinter camper van.
Sprinter Van Model
I got the 144″ Sprinter, which is the shorter model of the two currently available. The 144″ Sprinter fits in a normal parking spot and is slightly more maneuverable in cities and in back roads.
I opted for the high roof, Cargo style van and added sliding door and back door windows. I added the 4×4 option (which currently has a significant waiting list) which has a 3.0 L, v6 diesel engine.
Sprinter Van Bed
Fitting all of my desired components into a 144” Sprinter (the smallest version of new Sprinters) was going to be a challenge. When I was coming up with the concept for the layout, there were a few different options for the bed.
The first option was a dinette. This would maintain the walkway and give me a place to work, but it would be near impossible to have a bathroom. Plus sleeping vertically meant that the entire back half of the van would be devoted to the bed. Considering I’m often by myself, I didn’t think it made sense to waste two full walls on a bed and a 6 seater dining table.
The next option was a platform bed, where the bed is built on a large platform with a bunch of storage underneath. This option would provide the most storage space but would again eliminate the option for a bathroom. The walkway also wouldn’t be maintained, and my work space would be an afterthought.
After doing a lot of research and looking at a ton of cool camper vans on Pinterest, I had the idea for a convertible couch/bed with a pop out table that faced the large side door. This would maintain the walkway and the open feel of the van, giving me space for a bathroom and galley along the back wall, and I could enjoy the views as I sat and worked on my blog inside the van.
With the couch and the passenger swivel seat, my van can comfortably seat 4-5 people. When it’s time to eat or do my work, I simply place the two table legs into pegs built into the floor and then set the table right on top.
If I was going to have to make the bed everyday, I wanted it to be super easy so I’d actually put it away every morning. So at bed time, all I have to do is remove and store the table, unhook the bed, and the bed slides right out in one swoop. Then the memory foam cushions from the back of the couch separate and lay flat resulting in a near queen sized bed at 60” wide x 76” long – meaning it can sleep two tall people very comfortably.

Sprinter Van Galley
I didn’t want to have to set up a Coleman stove every time I cooked, so I opted for a permanent two burner galley. My stove is made by Ramblewood Green (Model GC2-43P). It’s a little large for the space, but it’s plenty powerful, cleans easily, and runs off of propane. The 1-gallon propane is stored in a cabinet under the sink and is enough for a week or longer depending on how much I use it.
I also wanted a place to do dishes (as well as brush my teeth, wash my hands, etc). The sink is stainless steel and made by Dawn USA (Model BS121307). It’s not too big, but big enough to throw some dirty dishes in. In order to do dishes without water getting everywhere, I chose the Kohler Simplice faucet (Model K-596-CP) with a pull-down spout, so I can direct the water as I’m scrubbing and rinsing.
Since the galley is on the back wall, it had to be built right over the wheel well. This reduced my options for a fridge, since the space wasn’t too big. The Isotherm CRUISE 65 Elegance is a medium-sized marine fridge that fit perfectly. At 2.3 cubic feet, it’s compact…but if you shop smart you can fit 4-5 days of food in there, plus a few beers. It’s also really quiet, and you can’t hear the motor.
The galley has enough counter top space to cut and prep food and has a set of 4 drawers and a deep storage space for pots and pans underneath.
Finally, on the back-end of the galley, there is a small fold down bar/counter where I can put food and drinks if I’m grilling or eating outside.
Sprinter Van Bathroom
I wanted a bathroom for a couple of reasons. I normally don’t mind going outside, but waking up in the middle of the night, getting dressed, and putting shoes on – just to go pee – is the WORST. Second, as solo female, I wanted to be completely self-contained for safety reasons. If I’m somewhere where I’m not super comfortable, I wanted to be able to close the curtains, lock myself in, and not have to go outside for anything. That way, no one has to even know that I’m in here by myself. Alternatively, if I’m parked in a city or outside a friend’s house, I can be totally out of their hair. So that was my reasoning behind having a toilet. Finally, having a hot water shower inside the van would make living in the van year round a more sustainable and enjoyable. Showering outside in the summer is fine, but in the winter without a shower, I’d be spending too many nights at friend’s houses or RV parks.
The bathroom is completely enclosed in the back corner of the van. It’s a little tight to sit on the toilet and have the doors shut, but even with my long legs, I fit in there ok.
The toilet is a Thetford Curve Portable Toliet (Model 92360 Porta Potti 550E). This means there is no plumbing associated with the toilet. You sit on it just like a normal toilet, do your business, close the lid, open the flusher, press the water button, and close the flusher. I’ve only gone #1 in it so far, but the deodorizer seems to neutralize all smells really well.
When the holding tank is full, there is an indicator letting you know it’s time to dump it. To clean it out, you simply separate the bowl from the holding tank, you unscrew the lid, and pour it down into the dump, just like you would for a black water tank. Then rinse, reassemble, and you are good to go.
The advantage of the porta potti vs a permanent toilet is that when I want to take a shower, I can take the entire toilet out so I don’t have to maneuver around it. Also if I want to go on a trip and need the bathroom to store large pieces of gear, I can leave the toilet behind.
The shower head is made by Camco (Model 43712) in chrome. I chose this shower head because it has an on-off switch on the handle. Paired with a 6 foot long shower hose, I can also use the shower to hose down gear or my feet outside. The shower floor consists of teak slats which are removable in case the drain to the grey water tank needs to be accessed.
Finally, I had a small fan installed in the bathroom to help dry it out after showering.

Water Tanks in my Sprinter Van
I have a 10 gallon water tank inside the van and another 15 gallon tank underneath the van outside. I need to find a solution to insulate the exterior tank for the winter so water in it doesn’t freeze, expand, and crack the tank. If anyone has ideas, I’m all ears!
I also have a 15 gallon gray water tank underneath the van where the shower and sink drain into.
Storage space in my Sprinter Van
The floorplan afforded quite a bit of storage space. I have a large floor to ceiling cabinet where I store all of my clothes, another big closet for gear, and a couple of drawers for my toiletries and electronic equipment. The galley has storage for kitchen items, and then overhead cabinets run along one entire side of the van. This is where I store food, books, and other random things. Underneath the bed you’ll find my systems and another large drawer where I store outdoor gear like camp chairs, my tent, sleeping pad, etc.
All of the drawers lock using these push buttons that prevent the drawers from sliding out while I’m driving.
I recently installed the raised headliner shelf by RB Components which fits right in the headspace above the driver and passenger seats. I was a little hesitant to give up the ample headspace in the drivers area, but this shelf has turned out to be a great compromise. It still gives access to the storage pockets above the visor and you only have to duck down a little bit when walking around up front….a worthy trade-off for the storage space I’ve gained. I’ve been storing bulky items like my pillows and blankets up there and it also makes it much easier when I’m making my bed every night.

••• Sprinter Van Solar System •••
In my van, I have a variety of electronics that need charging, and I wanted to be able to power all of my gear with solar. On the roof, I have 2 Grape 160 watt remote solar panels (MODEL GS-S-160-Fab8) that power up 3 Vmax SLR 125 Amp Hour batteries ( (MODEL VMAXSLR125) – for a total of 375 Amp Hours. This should be enough to keep me off the grid and charge my basic electronics for 4-5 days in cloudy weather…Stay tuned for an update on that.
***UPDATE: I swapped out my solar panels for two smaller panels made by Zamp. Stay tuned for an updated post***
The solar controller is the Midnite Solar Kid with a temperature sensor. This has a screen that tells me the status of the batteries and how many watts are being taken in by the panels.
In order to use any of the stored power, you also need an inverter. I use a Magnum continuous inverter/charger (MODEL MS2012).
The lights are all LED and powered by a few different switches. There is also track LED lighting that runs along the floor and ceiling that is really nice for evenings when I want some mellow mood lighting.
My ceiling fan is a Fantastic Fan (Model 2250). It is super powerful and can either pull air in on a hot day or blow smoke and smells out when I’m cooking.
The front of all of the cabinets is reclaimed barn wood, floors are dark bamboo, and the shower floor is made of teak. If you are looking for a source of reclaimed barn wood, there are lots of sites on the web that you can source it from.
