ProMaster vs Sprinter vs Transit: Which Van is Best for Homemade Campers?
When planning your first or next camper van conversion, choosing the right base vehicle is one of the biggest decisions you’ll make. The van you select will determine not only the layout and comfort of your living space but also how you travel, from fuel efficiency and off-road capability to repair costs and available space.
Among the most popular choices for homemade campers, three models dominate the North American market: the RAM ProMaster, the Mercedes Sprinter, and the Ford Transit. Each of these vans offers unique advantages for different needs and budgets. Whether you’re building your own camper van from scratch or planning to install a modular conversion kit, understanding these differences is key to making the right investment.
Let’s dive into what makes each of these vans shine, and which one we at Roadloft recommend for your next adventure.

RAM ProMaster: The King of DIY Camper Van Conversions
Why DIY builders love it
The ProMaster’s boxy shape and straight walls make it one of the easiest vans to convert. Unlike curved models such as the Sprinter or Transit, the ProMaster’s vertical sidewalls create a true rectangular living area. This means every inch of space can be used efficiently, ideal for modular setups, pull-out beds, and clever storage systems.
Its front-wheel-drive layout also gives it a major advantage: it allows the floor to sit lower, creating more standing height inside without adding overall vehicle height. For travelers who don’t want a towering van but still crave headroom, this is a game-changer.
Key advantages
- With the widest body in its class, you can install a full-size bed sideways, freeing up space for a larger kitchen or storage area.
- Simple mechanical design, easier to maintain and repair across North America.
- Great traction, front-wheel drive performs well in moderate winter or gravel conditions.
- Affordable to buy and convert, often thousands less than a Sprinter.
- Perfect for modular kits, systems like Roadloft’s camper conversion fit seamlessly thanks to its square geometry.
Potential downsides
- Lacks the refinement of a Mercedes camper van in terms of ride quality and luxury feel.
- Not as fuel-efficient as diesel Sprinters on long highway trips.
- Older models don’t offer all-wheel drive (available only from 2023 onward).
Verdict
The ProMaster is an outstanding platform for homemade campers who want simplicity, space efficiency, and cost control. It’s also our top choice at Roadloft for anyone seeking a practical, modular camper solution without complex modifications.
Mercedes Sprinter: The Luxury Camper Van Experience
The Mercedes Sprinter camper van is often considered the gold standard of van conversions. It’s a staple among professional upfitters and high-end vanlife enthusiasts who prioritize comfort, power, and durability.
The Mercedes camper van stands out for its refined driving experience, advanced features, and multiple configurations. Available with diesel or gasoline engines, 4×4 or AWD drivetrains, and various lengths and heights, it offers unmatched flexibility for customization.
If your goal is a full-time vanlife setup or extended off-grid travel, the Sprinter’s reliability and power are hard to beat.
- Diesel efficiency. The Sprinter’s diesel engine delivers strong torque and better fuel economy for long journeys.
- All-wheel drive (AWD) option. Perfect for off-road or winter adventures.
- High roof option. Provides comfortable standing height, even for taller travelers.
- Prestige and resale value. Owning a Mercedes camper van carries strong brand recognition and holds resale value better than most competitors.
- Professional-grade build options. Many luxury converters and expedition brands, like Winnebago and Revel, use the Sprinter chassis as their base.
- High maintenance cost. Parts and service are expensive, and finding a Mercedes-certified mechanic in rural areas can be challenging.
- Complex electronics. Great for comfort but not ideal for DIY modifications.
- Narrower interior width. Unlike the ProMaster, you’ll likely need to build the bed lengthwise, sacrificing space.
The Sprinter camper van is the best choice if you want a premium, long-term travel vehicle and don’t mind the higher investment. It’s ideal for professional conversions, overlanding builds, or full-time travelers who want comfort in every mile.
Ford Transit: The Reliable All-Rounder
The Ford Transit has become one of the most popular base vehicles for both commercial use and homemade camper builds, thanks to its reliability and widespread service network.
With multiple lengths, roof heights, and engine options, including an efficient EcoBoost turbo, Transit offers the flexibility to adapt to different camper styles. It’s especially appreciated for its available all-wheel drive and modern driver-assist features.
- Powerful performance. The 3.5L EcoBoost engine delivers impressive power, perfect for towing or mountainous terrain.
- All-wheel drive available. Great for moderate off-roading or winter conditions.
- High roof and extended versions. Plenty of headroom and cargo capacity for conversions.
- Strong service network. It is easy to find parts and mechanics anywhere in North America.
- Refined driving comfort. Handles more like an SUV than a commercial van.
- Curved walls. Interior buildouts are trickier compared to the ProMaster’s flat walls.
- Limited width. Like the Sprinter, fitting a bed sideways requires wall flares or creative framing.
- Higher initial price than the ProMaster, especially for AWD models.
The Ford Transit is perfect for travelers who want a balance of comfort, accessibility, and technology. It’s a solid choice if you want modern features and plan to travel across varied terrains.
