At the core of every van we build is our unique infrastructure, designed to enhance both the vehicle’s structure and overall build quality. Tailored to each custom design, our framework provides the flexibility needed for personalized creations. We incorporate sound damping and insulation to ensure a quiet, comfortable ride with optimal temperature control. These essential features contribute to a more durable and higher-performing vehicle.

Every van features full wall and ceiling paneling, along with a factory headliner. These panels are finished with wool insulation and a durable interweave fabric of your choice. With a wide range of color options for each fabric, all our materials are rigorously tested and designed to withstand the test of time.

Each van is equipped with expertly finished flooring and wheel well covers, crafted from high-quality materials to suit your preferences. We offer a variety of durable, adventure-ready flooring options, allowing you to select the style and color that best complements your custom build. Designed to withstand the rigors of any journey, our flooring solutions provide both functionality and aesthetic appeal, ensuring your van is ready for every adventure.

Illuminate your van with versatile lighting options designed to enhance any adventure. Each custom build includes thoughtfully placed lighting solutions, from ceiling fixtures to additional lights in key areas like the garage, galley, and entryway. With options ranging from dimmable LEDs to halo and strip lighting, we offer endless possibilities to create the perfect ambiance for your travels, ensuring your van is as functional as it is stylish.

  • The Heating

  • The Water

Reliable power is the backbone of any adventure van, providing the energy needed for lighting, appliances, and off-grid living. We offer a variety of power solutions to fit your unique needs, from compact systems for weekend trips to robust setups for extended off-grid adventures. Options include lithium battery systems, solar panels, inverters, and shore power connections. Whether you're running an induction cooktop, charging devices, or powering an air conditioner, our systems are designed for efficiency, durability, and ease of use, ensuring you’re never without the energy to fuel your journey.

Staying cool on your adventures is essential for comfort, especially in warmer climates. We offer a range of cooling solutions tailored to your needs and adventure style. Whether you require the power and efficiency of a 12-volt air conditioner for consistent climate control or the versatility of a MaxxAir fan for enhanced ventilation, we have options to keep your van comfortable in any environment. These systems are designed to optimize airflow, reduce interior heat, and ensure a pleasant living space, no matter where the road takes you.

Staying warm on your adventures is essential for comfort and functionality, especially in colder climates. Our heating solutions focus on high-performance diesel-fired systems, such as Aqua-Hot and Rixen, known for their reliability and efficiency. These systems provide consistent heat while conserving energy and fuel, making them ideal for off-grid living. Whether you’re warming up your living space or heating water for showers and cooking, our heating options ensure a cozy and comfortable experience, no matter the conditions.

Access to water is essential for any adventure, and our custom water systems are designed to meet your needs, whether you’re off-grid for a weekend or on an extended journey. We offer water tanks ranging from 20 to 40 gallons, providing ample capacity for drinking, cooking, and showering. Paired with efficient plumbing systems, these tanks ensure reliable water storage and flow, so you can enjoy the comforts of home wherever the road takes you.
