Mercedes Sprinter (170WB,  High Roof, Regular or Extended length)

Starting At: 45 000$ USD (170WB, High-Roof, 9990lbs GVWR, V6 Engine)


Mercedes Sprinter

Mercedes Sprinter

This is the most popular option for RV conversion. There is a very active online community so there is plenty of information & resources available online to assist the conversion effort. The used market is filled with Sprinters, mostly due to commercial vehicle retiring, so finding the vehicle that fits your needs and budget is facilitated. The initial buying cost & maintenance cost is high, but this does not seems to discourage people from choosing this option: you get a high-end, nice looking van with enough torque and still low MPG, that is nice to drive and that will keep a good value over time.

Since 2014 Mercedes propose 2 engine options:

  1. Diesel 2.1L I-4 (161 hp, 264 lb-ft of torque, 7 speeds transmission)
  2. Diesel 3.0L V-6 (188 hp, 325 lb-ft of torque, 5 speeds transmissions)

The 2.1L I-4 offer better MPG and smooth drive with its 7 speeds transmission. Users report 25 MPG with the 4 cylinders as opposed to 20 MPG for the 6 cylinders.

Sprinter Ressources:


Ram Promaster (159WB Extended, High Roof, Diesel 3.0L V6)

Starting At: 35 000$ USD (159WB, High-Roof, 8900lbs GVWR, 3.6L Engine)


Ram Promaster

Ram Promaster

The Promaster is relatively cheaper to buy than the Sprinter, but the maintenance fees are not that cheaper since this is a Fiat engine. The Promaster is FWD Drive, a feature appreciated if you plan to use it during winter. The Cargo volume is higher than the Sprinter due to the wall arrangement: compared to the Sprinter, the walls of the Promaster are almost vertical, the distance between the wheel wells is larger and the floor is lower (at ground clearance detriment). The squared angled walls will sure help when building the interior. Since it is a relatively recent vehicle, there are not as many options on the used market compared to the Sprinter.

Ford Transit (148WB Extended Length, High Roof, Gasoline 3.7L V6)

Starting At: 39 000$ USD (148WB, High-Roof, Extended-Length, 9000lbs GVWR, 3.7L Engine)

Gasoline? Yes. There are currently NO diesel on the used market in our area, but plenty of gasoline ones. Rental fleet are getting rid of last year models so the price is RIGHT. Of course diesel is cheaper at the pump, but here is a reality check: gasoline engine are simple. No fancy antipollution system and no fancy turbos (note: the 3.5L Ecoboost option has two turbos, but not the 3.7L). This is a major advantage if we want to travel to remote places. Another positive point: Ford dealerships are all over the place. If things goes wrong, the chances that there will be a Ford dealer near is much higher AND the parts will be much cheaper than for the Sprinter/Ram. For these reasons, we’re tempted. Note that feedback from users is positive: the van “drive like a car” (we confirm) and it is a quality build.

Ford Transit!

We were initially looking for a used Sprinter, then we started worrying about servicing issues. What if the van breaks down in no-where-city, Alaska? And what if the van breaks down in San Francisco… we are close to a dealer, but this is a Mercedes dealer we’re talking of! They offer free espresso when you stop by, but i’d rather go to Starbucks, it’s cheaper…

Then we started looking for a used Ford Transit. For a similar price to the Mercedes Sprinter, we would get a year old van with almost no mileage to the odometer, with some warranty left. Nice! We spent a few months searching actively to realize 95% the vehicle have no option at all: no cruise control, no side or rear window, no Limited Slip Differential, no high-roof & extended length…

So we built the Ford Transit of our dream (well kind of) on the Ford website. Darn, too expensive. We craved for a free coffee but the Mercedes dealer was closed, so we went to a Ford dealer instead. We had our coffee and meanwhile, we realized the Ford dealer was able to offer a much lower price than what we’ve seen on the Ford website. For about 8000$ more than a used van, we would get a brand new, fully warrantied, fully loaded van (see our Van page for all features). And with a low interest, long-term financing that would give us some slack. DEAL!

(As it turns out, ordering a Transit is not an easy task… we have a few tips on how-to order your van here)



First month on the road review: 

(The following text is extracted from

After speaking with some Sprinter folks, we’re relief we went for the Transit as we don’t expect major maintenance costs. Now that we’re fully loaded (see our Weight Report) and that we reached the west side, we’re definitely not getting KOM on the climbs with our 3.7L engine, but it still does the job. It helps a lot to use the SelectShift (manual shifting) because we find that the programming waits too long before downshifting to a lower gear while going up a hill (with cruise control turned on); by the time the Transit “decide” to downshift, we already lost too much speed and it has to downshift 2 gears instead of one. We’re still happy with our 3.7L, but we might hesitate for the Ecoboost option if we had to start over again…

We’re doing 20 MPG when crossing the prairies (no hills AT ALL, going at 62 MPH), then about 16-17 MPG in the mountains (again we never exceed 62 MPH, because we’re not in a hurry…), which is somewhat disappointing. But then, we have nothing in our favor –> High weight, High-Roof, All-Terrain tires, 4.10 transmission ratio.

    Regarding the promaster, there are several engines available. The standard engine is a 3.6 L V-6 (gas) with an automatic 6-speed transmission made by Dodge and used in many of their vehicles, and is apparently quite reliable. I have to say I love the front wheel drive 🙂 I do not think any of their engines these days is a Fiat, even the diesel.

    Do you have any resources for the 4.10 gear ratio decision? Currently in design phase and planning to go with the EcoBoost and 3.31 ratio as it seems to be the consensus unless we’ll be towing. That said, 3.73 is another option – curious your input here.

      EcoBoost is an excellent choice if you don’t mind the higher price tag!
      For the High-roof, extended length with 3.7 engine, there is no decision to make as the 4.10 is the only option! 🙂

    I diligently did my research on all three vans: Sprinter, Transit and ProMaster; test drove all of them and hands down the Transit came out on top so you guys definitely picked the right one. Thanks for putting together such a professional website. I’ll be referencing it while building my mini-house on wheels. And as an artist, I appreciate the quality of your photographs. Cheers. PS.

    Just my 2cents worth. I am an expeditor and drive in excess of 100k miles per year. I have a Mercedes sprinter 2500 that has the 5 cylinder turbo diesel. I get about 24 miles to the gallon when I’m empty and 20-22 with a load. It’s not unusual for my loads to reach 4000lbs. The turbo diesel is fast, economic, and has no problem pulling a load up a mountain. With all that said, my new van (which I get February 1st) is a Ford Transit 250. It is 173 inches from back of seats to the rear doors.This one has a 6 cylinder turbo diesel. I have a number of expeditor friends that have these and I have been told they are getting 30+ miles to the gallon WITH a load. Also… I do live in my van. I am telling you this because my sprinter has cost me a small fortune in repairs. When it breaks down on the road it is painfully expensive. So Ford it is. Just my thoughts. GL all on your adventures. If you see a big Ford Transit with an Ole Miss sticker on the back…say hello.

      Hi David, thanks for your input!
      Your story pretty much confirms my expectation about the Sprinter: great mileage, great van… until it breaks down then it costs a fortune.

      I’m surprised about your numbers for the Transit. I heard people are getting around 14-18 MPG with the 3.5 Ecoboost. Source:

      With our 3.7 engine, we’re getting 15 MPG on average (we’re almost 9000 GVW, high-roof, extended length, 4.10 transmission ratio).

      Have a good one!

      One of our main requirement was simple mechanic, if we ever want to drive to Patagonia or something… Diesel engines are super reliables, it’s their anti-pollution system that are problematic. Before this trip, I had a diesel Jetta which I really really liked; great power, great mileage. The only repair had to do with the anti-pollution/exhaust.

      I think it’s a personal choice; all the engine options are good!

      We have no problem with motion, either in cross wind or parked. Of course the Transit has more wind effect than a small car, but it’s not been an issue for us.
      I doubt the dually will help in this department, you might want to look at the 350 instead of the 250 (stiffer springs maybe?).
      Good luck

    I’m going through the process of researching and purchasing a Transit at the moment for similar reasons, I considered the vans you did (&NV2500) and I came to similar conclusions.

    You might consider posting the price ranges of each van as I’m sure this is a large consideration for many people arriving at this page.

    Also, have you guys looked at the Paseo? It’s the Transit-based Winnebego, really nice but waaaay too much money (~130k$). Still, I love it as a design reference. Next to yours, it’s one of my favorites.

    Hello Antoine.

    We are in the research stage before heading down a similar path with a Transit and live in the Foothills of the Rockies.

    Do you think the dually would be better or worse for winter traction?

    We would be using the BFG tires that seem to be becoming the standard tire for Transit and Sprinter conversions.

      Antoine Reply August 8, 2017 at 7:56 pm

      I’m no expert, but I don’t think a dually is better in snow; winter tires are actually generally a bit narrower. The dually is better for heavy load. Sorry I’m not much help; i’m sure folks on the would help!!

    Hi, great website. We’re also considering going a van and are currently going through the same cost “issues” as you did. Great to hear talking to a dealer can get your a great discount.

    Back on the 4wd though. We’re in the Canadian Rockies and I’ve been stuck getting out of a campsite carpark in the winter with a 2wd people mover before after some overnight snowfall. Couldn’t get it up the small incline onto the hyw. Now that you’ve used it a bit, any of those sort of concerns?

    • Comment by Antoine

      Antoine Reply August 1, 2017 at 6:31 am

      We haven’t use the Transit extensively in the snow so far, since we were in conversion-mode. The poor traction is a concern, but the 4×4 was just out of our price range. Since we bought the van new, we ordered the LSD (Limited Slip Differential) so when a rear wheel is spinning, some power is transferred to the other wheel as well. It’s no 4×4, but it helps a lot.

      That being said, we spent two week in the Chic-Chocs chasing the snow and the Transit got us where we wanted. Just don’t expect it to be an offroad machine. We found that a layer of medium-packed snow over a layer of ice is the worst; and if you are trying to take off on a small incline (like you mentioned), you won’t go anywhere (once you’ve got some speed it’s fine). On paved roads, we had no issue at all (but we don’t live in the Rockies!).

      It will be up to us to manage the traction “issue” by:

      1- Carrying snow-chains in the van (we have the Konig chains, formely designed by Thule:
      2- If possible, choosing a parking spot that is slightly descending (so if it snows overnight, it will be easier to take off in the morning).

      We’ll see how it goes!

    Sprinter,ProMaster, Transit….Having owned Mercedes since 1985, of course it was going to be a Sprinter. Thankfully, I spoke to a gentleman that had 43 of them, with a courier service and 40 out of 43 had exhaust (endless $$$ spent in the Mercedes shop, without a fix in sight)problems. 125,000 miles was the magic number when problems started. He traded them in over 18 months and got have ProMasters and half Transits. The transits ended up having the fewest problems. That is the reason I just ordered the High Roof, extended Transit. That for a dyed in the wool Mercedes car owner over the past 30 years.

    Great build site! Very very helpful and informative. A few followup questions since you have nearly a year? experience and have been through the winter.
    (1) Any regrets not having 4×4?
    (2) Are you finding the extended body to be acceptable in terms of handling and capability vs. shorter long body?
    (3) Find any vehicle options you wished you would have purchased or any options you find you didn’t need?

      1) No regret so far, i think the LSD will take us where we want. If you have the budget for the 4×4, it sure will provide extra confidence!
      2) We’re very glad we went with the extended length! We don’t mind the extra space it gives us since we plan on living in the van for at least a year. If you’re a weekend warrior, i guess the shorter-long-body is fine too.
      3) Nop, except the heating seats option that was not available on the 2016 Transit 🙁

But most of the Ford cars with V6 and 4L engine were not so reliable in the past! So my question, is the 3.7L a new more reliable Ford engine? Something we can drive for 250 000km without worrying about?!

    Thanks again

      We debated a lot on which engine to get… our main requirement was RELIABILITY over performance and according to our research, the 3.7L is all about that. There is nothing too fancy and complex about this engine and our common sense tells us that’s simplicity is the key to reliability! Less features = less potential for failures! Also, it’s been going for a while and data gathered seems to point in that direction. We’re very confident that our 3.7L will last forever with adequate maintenance 🙂

      That being said, we heard very good things on the 3.5 ecoboost. It’s a good engine but if it fails, you need to find competent & well trained mechanics to work on it…

      Hi Paul,

      of course the 4WD was considered, this is our dream van after all! But a dream van cost real money, so we had to let go the 4×4 option 🙁
      We are not 4×4 enthusiast; the purpose of the van is to bring us to remote trail heads and ski slopes. With planning and care, we should be able to go to most places without getting stuck. Heck, we’ve been using our Jetta (which has low ground clearance) for that purpose for the last few years without (most of the time!) getting stuck! Therefore, the Ford Transit with the KO2 and some chains should be alright 🙂

      At the time of writing these lines, the 4WD option is not offered by Ford so you would have to use the service of trusted aftermarket up-fitter such as Quigley. I believe the cost is around 12 000 US dollars for the 4×4 conversion.
      The Mercedes Sprinter now has the 4×4 OEM option. We had a look at it, but the price turned us down.

      Thanks for joining the conversation 🙂

To make a long story short, we chose the Ford Transit because we wanted easy & cheap maintenance (Ford dealers are all over the place and other shops should be able to work on it too), simple mechanic (we opted for the 3.7 engine, gasoline and without turbo), because the Transit is really nice to drive and mostly because it is much cheaper to buy than the Sprinter.

    I’m just trying to decide on what van to get. I was only thinking sprinter as the existing adventure van community is so extensive. A friend suggested I look at the Transit. I agree with your points why it makes sense. I travel to the Baja from Calgary and the access to Ford service would be a big bonus. There is little incentive for fuel economy given the maintenance costs of the MB diesel. My question is did you opt for the 3.7 for the simplicity? I’m leaning toward the Eco Boost as I’m concerned the 3.7 won’t have enough torque once the van is loaded. I’m also leaning toward the long body instead of the extended. Could you share your thoughts on your decision making? I kind of agree with the rationale of the couple on on van size, but always value another perspective.

      admin Reply July 25, 2016 at 9:03 am

      Hey Darrel,

      The primary reason we chose the 3.7 is SIMPLICITY. We are aware that the Ecoboost engine has very good reviews and that it seems to be a fun and reliable engine, but still, less features = less potential for failures. A friend of mine used to work as a mechanic at a Ford dealer; he agrees the Ecoboost is a good engine, but he also mentioned it is a very sophisticated thing: you need someone skilled and equipped with the right tools to work on it. Another reason we went with the 3.7 is the price: we rather save the money and invest it on nice features on the van 🙂

      About the torque. I love my VW Jetta 2.0 TDI. The consumption vs power is ridiculous. It’s a nice car that is always asking you to go faster. Fast = Fun. We quickly realized that the Transit is a different beast: the equation is Smooth = Fun. We found that the Transit drives well when we follow the speed limits, accelerate smoothly, take sharp turns smoothly, etc. It drives well, but it is not sporty by any means. In addition, this is our vacation vehicle: there is no rush! Therefore, we think the 3.7 will suit OUR needs!

      The length of the van is a personal matter. We chose the extended length because the primary use of the van will be for out-of-civilization trips. We favored living comfort over drivability (if we used the van primarily in urban areas, we would have opt for the short one). After driving the van for almost 2 months, we find it is quite easy to park if you don’t mind walking a little bit.

      So far, we’re pleased with our selection, but at the time of writing these lines our conversion is not completed yet. Time will tell.

      Good luck with your project!
