The Original Modular Sprinter & Transit Van Conversion System
When people search for a Sprinter van conversion kit or a Ford Transit camper conversion system, what they’re usually trying to avoid is chaos — piecing together insulation from one company, wiring from another, wall panels from somewhere else, and hoping it all works together.
Adventure Wagon changed that.
We built the first true modular van interior system anchored by a steel A-Frame foundation—a structural backbone that reinforces the van and gives every component a proper mounting point instead of relying on thin factory sheet metal.
And we’ve been refining that system longer than anyone else. That experience shows up in the details: the cleanest fit and finish on the market, smarter engineering that maximizes every inch of usable interior space, and manufacturing efficiencies that only come from years of iteration. The result is more room inside the van, better integration between components, and a camper van conversion kit that feels solid, quiet, and professionally finished—whether you install it yourself or have it installed.
No exposed cut metal.
No raw panel edges.
No guesswork with wiring.
No screwing cabinets into thin sheet metal and hoping for the best.
The Full Interior Kit is a complete system designed to work together. Here’s exactly what’s included and why each piece matters.
Steel A-Frame Foundation
The Backbone of Our Modular Van Interior System
At the core of every Adventure Wagon build is the steel A-Frame: a precision-engineered support structure installed throughout Mercedes Sprinter and Ford Transit vans. We utilize factory mounting points wherever possible to minimize drilling into the van body and ensure precise, repeatable fitment throughout the entire interior system.
This isn’t decorative framing. It’s a structural system that:
- Reinforces the van body
- Distributes weight properly
- Reduces flex and vibration
- Creates solid mounting points for walls, ceilings, beds, and gear
Because every major component connects to steel instead of sheet metal, your van conversion feels secure on the road. Fewer rattles. Less movement. More confidence.
It’s also what makes the entire system modular. The A-Frame allows you to mount beds, storage, and accessories without compromising strength.
Integrated L-Track System
Built-In Flexibility for Any Camper Van Layout
Bolted directly to the A-Frame is our integrated L-Track system, which turns your cargo van conversion into a reconfigurable platform. It opens up the kind of flexibility that makes a van truly yours. Mount it, move it, and rethink it whenever your adventure changes.
Our L-Track allows you to securely mount:
- MOAB bed rails
- Mule Bag overhead storage
- Gear accessories
- Future cabinetry or custom additions
Whether you’re building a weekend camper van, a family adventure van, or a gear hauler, L-Track lets you evolve your layout without drilling new holes in your vehicle.
For anyone planning long-term van life, that flexibility matters. Your needs change. Your interior should too.
Available in bare aluminum or black anodized finish.
Plug-and-Play 12V Electrical Harness
Simplifying the Hardest Part of a DIY Van Conversion
Electrical is one of the biggest barriers to a van build. That’s why our camper van wiring harness comes pre-measured, labeled, and ready to install.
The 12V harness routes power through the van’s pillars and ceiling to support lighting and outlets, then connects directly to your battery system. It’s engineered to integrate with the power solution of your choice but pairs seamlessly with our all-in-one GOAT Locker, creating a centralized electrical hub that keeps wiring protected, organized, and easy to access.
Included components:
- All the wires you need to install your electrical system
- Blue Sea Systems corrosion-resistant USB and 12V outlets
- Dual red/white dimmable LED ceiling lights
This is not a bundle of loose wires. It’s an organized, integrated electrical system designed specifically for Sprinter and Transit van conversions.
Insulation & Sound Dampening
Comfort Built Into Your Van Conversion Kit
A comfortable camper van starts behind the panels.
Each Adventure Wagon Full Interior Kit includes:
- Pre-cut and labeled Hydrophobic 3M Thinsulate insulation
- Reflectix low-E insulation on the back of every wall panel
- Hushmat sound dampening applied directly to the van’s metal
Together, these materials help regulate temperature in hot and cold climates while significantly reducing road noise and vibration.
For anyone converting a cargo van into a four-season camper, proper insulation isn’t optional. It’s foundational.
Precision-Cut Wall & Ceiling Panels
Clean Trim. Professional Finish. No Trimming Required.
Our van interior panels are engineered specifically for Mercedes Sprinter and Ford Transit platforms. Every panel is precision-cut, so you’re not measuring, trimming, or improvising.
Standard materials include:
- Marine-grade 1/4" Baltic Birch plywood
- Custom molded ABS trim upholstered in durable Marathon tweed
- Black hexa-ply plastic-coated plywood for a modern, highly durable finish
Upgrade options include:
- Finished bamboo panels
- 100% bamboo ceilings
The molded trim system eliminates exposed metal edges and unfinished transitions, resulting in a clean, cohesive interior that feels purpose-built rather than assembled. And because each panel is engineered to fit precisely, the system also maximizes the space behind the walls, giving you more usable room inside the van.
Ventilation & Climate Control
Ready for Off-Grid Travel
Every Full Interior Kit includes a MaxxAir Deluxe roof fan for airflow and ventilation, essential for any Sprinter or Transit camper conversion.
Optional Espar diesel or gas heaters are available for four-season builds. Whether you’re camping at elevation or traveling in colder climates, the system supports year-round comfort.
Hardware, Templates & Step-by-Step Guidance
Designed for DIY Builders and Professional Installers
Your van conversion kit ships via freight on a custom pallet with all parts labeled, protected, and organized.
Included with every kit:
- All required hardware
- Mounting templates
- Detailed installation instructions
- Step-by-step video guides
The system is intentionally designed for DIY van conversion using common tools like a drill, impact driver, and tape measure. The only specialty tools required are a rivnut setter and rivet setter, and we provide clear guidance on selecting and using them.
If you prefer additional support, we offer a partial install option where our team handles the A-Frame installation and major hole cutting before you complete the interior.
And if you have questions, our tech support team is available by phone or email. You’re never left guessing.
