Custom Van Conversions Built for Your Lifestyle

Are you looking to convert an ordinary cargo or passenger van into a fully functional camper, mobile office, or adventure vehicle?

Bitterroot Builds is a Utah-based team of experienced custom van builders specializing in Sprinter, Transit, and Promaster van conversions. Since 2017 have been transforming blank vans into purpose-built vehicles designed around how you travel, work, and live.

Many "custom" vans are built for the Instagram shot, not the high desert or the sub-zero trailhead. You’ve seen the DIY kits that rattle on the washboard roads of Moab and the wooden cabinetry that warps after one season in the Wasatch humidity.

At Bitterroot Builds, we don’t just build "campers." We engineer mobile sanctuaries designed to withstand the extremes of whatever your adventure throws at you. Whether it’s a Mercedes-Benz Sprinter, Dodge Promaster, or a Ford Transit, we transform raw chassis into uncompromising adventure rigs.

Specialized Engineering for Infinite Exploration

When most people envision their dream van, they see the beautiful kitchen and the warm interior. But in a vehicle facing constant vibration and 100°F temperature swings, what’s behind the build determines the life and enjoyment of your van's interior.

  • Aerospace-Grade Skeletons: We use 80/20 T-Slot Aluminum framing for maximum strength with minimal weight
  • True 4-Season Resilience: Advanced thermal envelopes designed for -10°F ski resorts and 100°F desert heat.
  • Agnostic Power Systems: Intelligent energy hubs (Victron, Ecoflow, Mastervolt) tailored to your specific off-grid needs.


The 80/20 Advantage: Why Aluminum Beats Wood

We’ve moved beyond the traditional cabinet shop. By engineering our cabinetry skeletons using 80/20 T-slot aluminum, we provide a foundation that is:

  • Lighter: Up to 1,000 lbs of weight savings compared to traditional all-wood builds, protecting your payload and fuel economy.
  • Stronger: Bolted directly to the van's chassis to eliminate the "settling," squeaking, and rattling common in wood-on-wood joints.
  • Resilient: Aluminum is impervious to moisture and rot, staying perfectly square through every season.
  • Modular: Unlike permanent wood structures, our T-slot architecture allows your interior to evolve as your needs change.


WHY WE BUILD CUSTOM VANS

Located in the valley of Salt Lake City since 2017, our shop is a laboratory for mountain living. Every design choice, from the wire gauge to the ergonomic flow of the galley, is informed by thousands of nights spent on the road. We don't just follow a blueprint; we obsess over the technical specs that ensure your safety and comfort in the wild.

Bitterroot Builds was forged from a simple necessity: the search for a rugged, self-contained basecamp. Our team’s background in mountaineering, mountain biking, and off-road travel taught us exactly where traditional camping solutions fail. We looked to the sophisticated European van market to find a better way, combining that research with our own backcountry experience to engineer 4x4 rigs that offer uncompromising comfort in demanding terrain. We build vans because we’ve seen what’s possible when your home and your vehicle become one."
