Before you get excited about solar panels and cabinetry, you need to choose the platform you're building on. This is the biggest financial decision you'll make in your van build, and it's worth getting right.
The conventional wisdom says you need a high-roof Sprinter, Transit, or Promaster. And yeah, standing up inside is genuinely nice. But that capability comes with a significant price tag - not just upfront, but in maintenance costs, parts availability, and complexity.
These are what most people think of when they picture a camper van build. They're the Instagram vans, the YouTube vans, the "this is a real van build" vans. And they're legitimately great vehicles for certain people.
But let's talk about what you're actually signing up for.
The Sprinter has been the gold standard for van conversions for years. It's what started the whole #vanlife movement, and there's a reason - they're genuinely excellent vans when they're working properly.
My take: Sprinters are genuinely great when they work. But the cost of ownership is significantly higher than domestic vans, and the complexity means more things can go wrong, and repairs are expensive when they do. If you have $50,000+ to spend on a used van and aren't bothered by expensive repairs, go for it. If you're trying to build affordably, look elsewhere.
The Transit is Ford's answer to the Sprinter, and it's become increasingly popular for conversions. It's newer to the US market (2015+) but has been sold in Europe forever. The high roof is the tallest of any van at 81" interior height.
My take: The Transit is probably the best compromise if you're set on a high-roof van. It's cheaper than a Sprinter, has better dealer support, and the interior space is excellent. The EcoBoost isn't as proven as an LS engine, but it's not terrible either. If I had $35,000-$35,000 to spend and wanted a high-roof van, I'd seriously consider a Transit.
The Promaster is based on the Fiat Ducato and is the cheapest way to get a high-roof van. It's also the widest of the three at 70"+ interior width — a genuine advantage for build layout. But it's the most compromised.
My take: The Promaster is the high-roof van I'd least want to own. The FWD is a huge limitation, the reliability is questionable, and while it's cheaper upfront, I'm not convinced it's actually cheaper over time given repair costs and poor resale value. If your budget is $20,000-25,000 and you're absolutely set on having a high roof, I'd rather see you buy a standard-roof Express for $10,000 and spend the other $15,000 on your build.
The Promaster's front-wheel drive deserves a deeper discussion because it's not just a minor specification difference - it fundamentally affects how the van behaves when loaded for camping.
In a converted camper van, almost all your added weight (batteries, water tanks, cabinets, bed platform, gear) sits behind the front axle — easily 1,000-2,000 lbs in the rear. When you drive up a hill, physics shifts even more weight rearward.
For RWD, this is great:
More weight on drive wheels = more traction where you need it. The heavier the load, the better it grips going uphill.
For FWD, this is terrible:
Less weight on drive wheels = less traction. Front wheels get lighter as you climb and can start to lose traction. Add snow or gravel and it gets worse quickly.
On flat pavement, FWD works fine. But in a loaded camper van, expect problems with:
If you plan to camp in winter anywhere with hills, access mountain campgrounds, or drive through Colorado/Montana/Utah in winter — the Promaster's FWD is a serious limitation bordering on disqualifying.
These are the vans that actually get work done in America. They're not sexy, they don't have high roofs, and they won't get you Instagram likes. But they're reliable, cheap to maintain, and they work. I own one, so I'm biased. But I'm biased because I've been really happy with it.
My take: This is the best bang-for-buck in van builds. For $8,000-15,000, you get a reliable platform that will last for years and won't break the bank to maintain. Yes, you give up standing room. But you gain financial security and simplicity. If you're on the fence about van life, start here. You can always upgrade to a high-roof van later if you decide you need it.
The Econoline (E-150/E-250/E-350, produced until 2014) fills the same niche as the Express. Similar price range, similar capability. The main difference: the 5.4L Triton engine has known issues — spark plugs can break off in the head ($500-1,000 fix), plus cam phaser and timing chain problems. The LS in the Express is more reliable.
If you find an Econoline with the 6.8L V10 at a good price, that's worth considering — the V10 is more reliable, but gets 10-12 mpg. Otherwise, the Express is the safer bet.
