The big three. The holy trinity of van life. If you're building a camper, chances are you're choosing between a Ford Transit, Mercedes Sprinter, or Ram ProMaster. Let's break down the real differences so you can stop doom-scrolling forums and actually pick one. 🎯
🔵 Ford Transit
Price range: $25K–$45K new · $12K–$30K used
👍 Pros: Best dealer network in the US, cheap parts, multiple roof heights and lengths. The EcoBoost engine is peppy. Easiest to get serviced anywhere.
👎 Cons: Rear-wheel drive means less interior floor space. The wheel wells intrude into the cargo area. Fuel economy is just okay.
Best for: Builders who want reliability, easy maintenance, and don't want to hunt for a mechanic.
⭐ Mercedes Sprinter
Price range: $40K–$55K new · $18K–$40K used
👍 Pros: The OG van life van. Diesel efficiency (18-22 mpg), tallest standing height available, premium build quality. Incredible resale value.
👎 Cons: Expensive to buy AND repair. The diesel emissions system (DEF/AdBlue) can be a headache. Mercedes parts cost Mercedes money.
Best for: Long-term travelers who prioritize fuel efficiency and don't mind paying a premium upfront.
🔴 Ram ProMaster
Price range: $30K–$42K new · $10K–$25K used
👍 Pros: Front-wheel drive = completely flat floor (builder's dream!). Widest interior of the three. Lowest price point. Tight turning radius for city driving.
👎 Cons: Gas only (no diesel option in the US). The Fiat-sourced engine worries some people. Lower resale value. Wind can push it around on highways.
Best for: Budget builders who want maximum interior space and the easiest platform to build on.
