ProMasters Are Great! But Here's Why We Don't Work on Them

ProMasters Are Great! But Here's Why We Don't Work on Them

We get asked about Ram ProMaster conversions regularly, and for good reason—they've been a popular budget option in the van life community for years. ProMasters are solid, capable vans with some real advantages like front-wheel drive traction and wide interiors. But at The Vansmith, we've made the strategic decision to focus exclusively on Mercedes Sprinters and Ford Transits. Here's why.

The Price Advantage Has Disappeared

The biggest reason people chose ProMasters was simple: they were significantly cheaper than Sprinters or Transits. That advantage has largely evaporated.

What Changed:

  • ProMaster pricing has increased substantially over the past few years
  • Ford has become much more competitive with Transit pricing and incentives
  • The price gap that once made ProMasters the clear budget choice is now minimal
  • When you factor in resale value, Transits often represent better long-term value

The Numbers Today:

A comparable Transit now costs only $3,000-$8,000 more than a ProMaster—a difference that's easily offset by the Transit's superior features, better resale value, and improved driving experience.

No 4x4 Option = Limited Adventure Capability

Colorado adventures demand capability, and more of our customers want the option to access remote locations and handle challenging conditions.

The Reality:

  • ProMaster only offers front-wheel drive—no AWD, no 4x4
  • While FWD performs surprisingly well in snow, it can't match AWD/4x4 for off-road access
  • Ford Transit offers intelligent AWD across the lineup
  • Mercedes Sprinter offers factory 4x4 options for serious off-road capability

For Colorado adventurers who want to access backcountry campsites, forest service roads, and remote locations, the lack of 4x4 capability is a significant limitation.

Why We Choose Ford Transit and Mercedes Sprinter

Ford Transit Benefits:

  • Excellent value proposition with competitive pricing
  • Intelligent AWD available across all models
  • Widespread service network throughout North America
  • Strong towing capability and reliability
  • Better highway driving experience

Mercedes Sprinter Benefits:

  • Maximum interior space and premium build quality
  • Available 4x4 for serious off-road capability
  • Excellent fuel economy and long-term reliability
  • Superior resale value
  • Most refined driving and living experience

What This Means for You
