Semi-Custom Campervans at OVP

SEAT 4 / SLEEP 4

At Overland Van Project, we design and build semi-custom campervans that reflect your lifestyle and spirit of adventure. Every van blends premium craftsmanship, true off-grid capability, and refined design to create a vehicle that’s as functional as it is beautiful.

Our Mazama and other core layouts serve as a solid starting point—but every build is uniquely yours. Choose your color palette, suspension system, power setup, and interior and exterior features to craft a van that’s perfectly suited to the way you travel.

All OVP vehicles are proudly built in Oregon — the land of no sales tax — and developed through nearly a decade of real-world experience and rigorous four-season testing. Every build is engineered for comfort, durability, and versatility, using only the highest-quality materials and proven construction methods, so you can stay focused on what matters most: the adventure ahead.

Every build is engineered for comfort, versatility, and durability, using only the highest-quality materials and expert craftsmanship, so you can stay focused on the adventure at hand.

This model is known as our Family Van, it comfortably sleeps four people, two in each of the bunk beds in the back. It also seats four legally in DOT-approved, JMG seats with 3pt harnesses so you can get to your destination safely and in comfort!  The Mazama is our most modular model; with a removable upper bunk, so you can seat 10 in your van; removable lower stringer so you can transport your bikes inside; removable seats if you want a little extra mobility when the kids are gone; and a hidden toilet compartment that can be used for storage if you don't need the loo.

No experience required.
  • POWER SYSTEM

    Every OVP vehicle is equipped with robust, adventure-ready power systems built to keep you fully charged wherever the road takes you. A 1000Ah 12V Victron lithium battery bank paired with a Victron 3000W inverter provides reliable energy for all your devices and appliances. Recharging is seamless via a second alternator, 400W Renogy solar panel, or shore power, giving you the freedom to stay off-grid longer without sacrificing comfort or convenience.

  • WATER SYSTEM

    OVP builds are engineered for true four-season comfort, with advanced insulation, precision seals, and rigorous systems testing to keep you cozy from -20°F to 100+°F. Our thoughtfully designed water system includes 33 gallons of fresh water and 14 gallons of gray water, paired with on-demand hot water for convenience wherever you go. Take advantage of the interior hid-a-way shower or step outside for an outdoor shower complete with a bamboo mat and ripstop curtain — so you can stay clean and comfortable no matter the adventure.

  • CLIMATE & COMFORT SYSTEM

    Stay comfortable in any environment with OVP’s full four-season climate system. The Velit 2000R 12V air conditioner keeps you cool in the heat, while the Rixens heat and hot water system and heated floors provide cozy warmth during cold weather. Continuous airflow and ventilation are ensured with the NomadicArk vent fan, creating a perfectly balanced interior climate no matter where your adventures take you.

  • APPLIANCES

    OVP kitchens are designed for effortless functionality and everyday ease. Keep food fresh in the Isotherm 130 stainless steel drawer-style fridge, cook anywhere with the Empava two-burner induction cooktop, and enjoy modern conveniences including a Trelino toilet and Starlink connectivity. Every element is thoughtfully integrated to maximize space, efficiency, and comfort on the road.

  • SEATING & SLEEPING

    Stay cozy and well-rested in your OVP Murphy bed, complemented by a RoamRest folding mattress for added comfort. The Super Pacific pop-top provides extra sleeping space when needed, while JMG 20" DOT-rated captain’s chairs add versatility and safety for daytime use. Every element is designed to maximize comfort, functionality, and adaptability — so your van works as hard as you do, whether you’re driving, dining, or sleeping.

  • PANELING & INSULATION

    Every OVP interior is finished with marine-grade paneling and engineered with a four-layer insulation system, delivering exceptional durability, thermal performance, and noise reduction. The result is a quieter, more comfortable cabin that’s built to withstand the demands of real adventure — season after season.

  • INTERIOR FUNCTION & COMFORT

    Every detail in an OVP build is designed to enhance everyday living on the road. A Lagun table with holster provides a versatile workspace or dining surface, while the drop-down exterior galley table expands your living area outdoors in seconds. Inside, an insulated cab curtain and Van Essentials window covers improve privacy and thermal efficiency, and Van Essentials rear door storage bags add smart, accessible storage right where you need it.

  • EXTERIOR UPGRADES

    OVP vans are built to tackle any terrain while keeping you comfortable and prepared. Toyo AT3 3-Peaks-rated 31" all-terrain tires and Evictus advanced suspension provide exceptional off-road capability, while Flarespace full flares increase interior room without compromising style or performance. A Flatline standard roof rack and Fiamma F45 manual awning expand storage and outdoor living space, complemented by CRL 10x33 awning windows and an AMA slider crew window for ventilation and natural light. For night or low-light adventures, the Extreme LED 50" light bar ensures visibility wherever the journey takes you.
