Comparison of Sprinter, Transit, and Promaster vans, highlighting their different sizes and body styles.
Key Questions to Guide Your Van Choice
Before diving into specific van models, consider these questions to narrow down your choices. Answering these might quickly reveal that one or two models don’t align with your essential needs, simplifying your decision process significantly. Understanding your priorities from the outset is crucial.
Budget Considerations
Budget is paramount. Establish a realistic budget early to avoid being swayed by appealing but unnecessary features. It’s easy to overspend, leaving insufficient funds for crucial interior fittings or exterior upgrades.
Factor in the long-term costs, including maintenance and part accessibility in your area. Different vans have varying maintenance schedules, impacting your overall ownership expenses.

New vs. Used Van
New vans come with a higher price tag but offer the reliability of a warranty, potentially saving on future repair costs. Financing is also typically easier for new vehicles.
Used vans can be budget-friendly, but thorough inspection is vital. A lightly used van with remaining warranty could be an excellent find, though less common currently.
Van Size Requirements
Consider your height and space needs. If you’re tall, the Ford Transit offers about 4 inches more headroom than the Mercedes Sprinter.
For horizontal space, Sprinters offer longer body lengths, ideal for more passengers or bulky gear. If you need maximum cargo capacity, the Sprinter may be preferable to the Ford Transit and Ram Promaster.
Long-Term Van Usage
Think about how long you plan to own the van. Diesel Sprinters are known for their longevity compared to gasoline-powered vans like the Ford Transit or Promaster.
If resale value is a concern, Sprinters often hold their value better over time due to their diesel engine and reputation.
Intended Van Use
Consider your typical driving conditions. For off-road adventures or snowy conditions, a 4×4 or AWD van is crucial. For coastal cruising, it might be less necessary.
Interior layout needs also depend on your van life style. Prioritize interior space for cooking and sleeping by choosing a van with a spacious layout and ample cargo volume.

Maintenance Considerations
Maintenance varies between van models. If you’re comfortable with DIY repairs, you might handle minor issues. However, extensive repairs can be costly.
Research owner reviews to understand common issues for each van. If anticipated repairs strain your budget, consider a more reliable option or one with a comprehensive warranty.
Transit vs. Sprinter vs. Promaster: Model Overview
Mercedes-Benz Sprinter
The Mercedes-Benz Sprinter is a long-standing favorite and a leader in the adventure van community. Despite a higher initial price, it’s recognized as the most refined van in its class.
For decades, Sprinters have been converted into mobile adventure vehicles and remain a top choice. As a versatile daily driver and weekend getaway vehicle, the Sprinter often surpasses competitors like the Ford Transit and Ram ProMaster.
Sprinters offer diesel and gas engines, with 2WD and 4WD options. This versatility, combined with advanced safety features and a wide range of upgrades, makes the Sprinter a prime option for van lifers seeking top-tier quality and extensive customization possibilities. It also offers the longest body length, providing maximum interior space for conversions.
Sprinter models come in various wheelbases, two recommended roof heights, and three body lengths:

Ford Transit
The Ford Transit is rapidly gaining popularity in the conversion van market. A major factor is the introduction of All-Wheel Drive (AWD) in newer (2020+) models. Previously, 4WD was a key Sprinter advantage, but Transit is now capturing a larger share of the market.
Newer Ford Transit models offer impressive features, including built-in power inverters for AC in the cargo area (still absent in Sprinters) and Ford’s advanced SYNC3 infotainment system. Modern Sprinters typically feature the MBUX infotainment system.
Ford Transits are available in both diesel and gas, with the Ecoboost engine praised for its performance and fuel efficiency comparable to the Sprinter.
Ford Transit models come in several wheelbase options, two recommended roof heights, and two body lengths:
- 148″ Wheelbase with Mid Roof
- 148″ Wheelbase with High Roof
- 148″ Extended Wheelbase with High Roof
The 148″ High Roof and 148″ High Roof Extended are most popular for conversions, while the 148″ Mid Roof is also gaining traction.
Ford Transit Van Dimensions

Ford Transit: Top Advantages
- Tallest Roof Option: Transit offers the highest roof in its class, ideal for tall individuals or storing bulky items.
- Familiar Driving Experience: The Transit drives more like a traditional truck or SUV, offering a familiar feel for many drivers.
- Wider Interior: Transit’s wider interior allows shorter individuals to sleep sideways without van flares.
- Extensive Service Network: Ford’s widespread service center network makes maintenance and repairs easier and often less expensive.
- Efficient Ecoboost Engine: The Ecoboost engine delivers good fuel economy and strong driving performance for a cargo van.
Ford Transit: Key Considerations
- Fewer Customization Options: Compared to Sprinters, Transits have fewer factory upgrade options for interior and exterior aesthetics, though aftermarket accessories like Transit roof racks are plentiful.
- Limited Used AWD Availability: AWD Transits are newer to the market (2020+), making used AWD models harder to find compared to Sprinter’s long-standing 4WD option.
- Lower Ground Clearance: Transit has less ground clearance than the Sprinter, making it less ideal for frequent off-road travel.
- Lower Fuel Efficiency than Sprinter: Transits are generally less fuel-efficient than diesel Sprinters.

Ram Promaster
The Ram Promaster, sometimes mistakenly referred to as a “Dodge Sprinter,” is distinct from the Mercedes Sprinter and offers its own set of advantages for van conversions. The Promaster stands out with its boxy, van-like shape, which simplifies interior build-outs. Its square interior maximizes usable space and comfortably accommodates sideways sleeping for most people without needing flares.
However, the Promaster has fewer aftermarket upgrades and lower ground clearance. It also lacks a 4WD or AWD option, limiting its off-road capabilities.
On the plus side, Promaster maintenance and parts are generally more accessible and affordable than for the Mercedes Sprinter. While Ford Transit has a wider dealership network, most US cities have Dodge/Ram dealerships and service centers.
The Promaster’s design aesthetic can be polarizing, but it’s a budget-friendly option for conversions not requiring off-roading or heavy hauling.
Promaster models come in several wheelbase options:
- Promaster High Roof 136”
- Promaster High Roof 159”
- Promaster High Roof 159” Extended
The 136″ and 159″ are the most popular choices for van conversions.

- More Affordable Option: Promasters are generally more affordable than both Transit and Sprinter vans.
- Wide Body: The wide body is convenient for sideways sleeping layouts, saving space and build complexity.
- Tight Turning Radius: Promasters excel with a tight turning radius, enhancing maneuverability in urban settings and tight trails.
- Growing Aftermarket: A growing selection of Promaster roof racks and accessories is becoming available.

Ram Promaster: Key Considerations
- No 4WD or AWD: The Promaster is only available in 2WD, front-wheel drive, limiting its performance on rough terrain or in snow. It’s best suited for paved roads and flatter areas.
- Lower Power: Promasters offer less power than comparable Sprinters and Transits and are not recommended for heavy towing.
Budget Breakdown: Sprinter vs. Transit vs. Promaster Pricing
Budget is a crucial factor in choosing your conversion van. Comparing MSRPs, the Promaster and Transit are generally more budget-friendly than the Sprinter. However, the Sprinter offers more standard features and a larger aftermarket for upgrades. A thorough feature-for-feature comparison is essential before making a final decision.
Mercedes Sprinter – $$$
The Sprinter has the highest MSRP of the three vans, typically starting $5,000 or more above similarly equipped Transits.
This premium price reflects the Mercedes-Benz brand, advanced safety technology, enhanced comfort features, and the vast aftermarket for interior and exterior upgrades. With a Sprinter, you have extensive customization options using professionally made parts.
For those prioritizing premium features and extensive customization from the start, the Sprinter is a strong choice. Ford Transit and Ram Promaster offer fewer initial aftermarket options.
Ford Transit – $$
The Transit offers a more affordable starting MSRP than the Sprinter and fewer standard aftermarket modifications. However, ample aftermarket options are still available to customize your Transit into an adventure van. Explore Ford Transit parts and accessories here >>
Top-tier Transit models increasingly offer features comparable to Sprinters, and with the introduction of AWD in 2020, the gap between Transit and Sprinter is narrowing.
Ram Promaster – $
The Promaster has a similar starting MSRP to the Transit, aligning with 2WD Transit models. It is less expensive than AWD Transits or 4WD Sprinters.
Technologically, the Promaster competes well, especially with its updated infotainment system in 2022 models.
Overall, the Sprinter justifies its higher price with greater refinement, built-in luxury, and comfort, maintaining its position as a leader in the van life segment.
Engine, Transmission, and MPG: Sprinter vs. Transit vs. Promaster
Mercedes Sprinter: Offers gas and diesel options, including 4-cylinder gas, 4-cylinder diesel, and 6-cylinder diesel models. The 6-cylinder diesel 4×4 is popular, and a new 4-cylinder turbocharged diesel with torque-on-demand AWD is available.
The 6-cylinder diesel achieves around 20 mpg with a 7-speed automatic transmission, while the 4-cylinder gas model gets about 17 mpg with a 9-speed automatic.
Sprinter | Engine | MPG Est. | Transmission | HP | Torque |
---|---|---|---|---|---|
6 Cyl 3.0L Diesel | 20 | 7 Speed Auto | 188 | 325 | |
4 Cyl 2.0L Gas | 17 | 9 Speed Auto | 188 | 258 |






Ford Transit: Also available in gas and diesel, with the 3.5L V6 EcoBoost being a popular choice for its balance of power and efficiency. Other options include a 3.5L V6 and a 2.0L Turbo-Diesel.
The EcoBoost engine provides a responsive driving experience, achieving 0-60 mph in around 6.8 seconds. Both the EcoBoost and 3.5L V6 models achieve about 17 mpg, while the 2.0L Turbo-Diesel reaches approximately 20 mpg, paired with a 10-speed automatic transmission across models.
Transit | Engine | MPG Est. | Transmission | HP | Torque |
---|---|---|---|---|---|
Gas 3.5L V6 Eco Boost | 17 | 10 Speed Auto | 306 | 400 | |
— | |||||
3.5L V6 Gas | 17 | 10 Speed Auto | 271 | 260 | |
2.0L Turbo Diesel | 20 | 10 Speed Auto | 210 | 369 | |
— |
Ram Promaster: Exclusively gasoline-powered, with a 3.6L V6 engine and 7-speed automatic transmission, achieving up to 17 mpg. It offers less torque than Sprinter and Transit diesel options, making it less suitable for heavy towing, but provides a tight turning radius.
Promaster | Engine | MPG Est. | Transmission | HP | Torque |
---|---|---|---|---|---|
3.6L V6 Gas | 17 | 7 Speed Auto | 280 | 260 |
Drivetrain Comparison: 4WD Sprinter vs. AWD Transit vs. FWD Promaster
Let’s compare the drivetrain options:
- Sprinter: Offers 2WD and 4WD models. The 4WD is technically an AWD system distributing 33% torque to the front and 67% to the rear. It can be disengaged but requires stopping and shifting into neutral.
- Transit: Available in AWD and RWD. The AWD system, introduced in 2020+, can dynamically transfer up to 100% of torque to either front or rear wheels and can switch between modes on the fly.
- Promaster: Only available in 2WD, front-wheel drive.
Both Sprinter and Transit offer good ground clearance, with Sprinter having a slight edge. While all three can handle off-road conditions with appropriate tires, they are not designed for serious rock crawling.
The Ford Transit’s AWD system is a significant advancement, allowing on-the-fly adjustments, a notable advantage over the Sprinter’s 4WD engagement process.
The Promaster’s lack of 4WD or AWD is a major limitation for many, making it less suitable for off-road or snowy conditions and best for paved roads.
Reliability, Warranty, and Service: Sprinter vs. Transit vs. Promaster
New Sprinter, Transit, and Promaster vans come with factory warranties covering repairs and maintenance. For used vans, look for recent models with remaining warranty coverage, and verify transferability.
Mercedes Sprinter Warranty:
- Basic: 3 years/36,000 miles
- Powertrain: 5 years/100,000 miles
- Outer-Body: 5 years/100,000 miles (corrosion)
Service can be less accessible for Sprinters outside major cities due to fewer specialized service centers.
Ford Transit Warranty:
- Basic: 3 years/36,000 miles
- Powertrain: 5 years/60,000 miles
Transit service is generally easy to access due to Ford’s extensive dealership network.
Ram Promaster Warranty:
- Basic: 3 years/36,000 miles
- Powertrain: 5 years/60,000 miles
Promaster service is also readily available at Dodge/Ram dealerships, similar to Ford’s accessibility.
