Heating & Climate Solutions
A reliable climate system is essential for comfortable, year-round overland travel. At White River Overland, we design and install heating and climate control upgrades for overland vehicles, including diesel heaters, air conditioning solutions, and insulation systems. Each component is thoughtfully integrated to manage interior temperature efficiently across changing weather and elevations. Whether you’re gearing up for skiing, traveling through the desert, or building a true four-season vehicle, our climate upgrades are designed to improve comfort, efficiency, and off-grid comfort.
Why Upgrade Your Vehicle’s Climate Systems?
-
Stay Comfortable in Cold Weather
Factory vehicle systems are not designed for extended stationary use. Upgrading with a dedicated heater allows you to maintain a comfortable interior temperature during cold nights and winter travel without relying on engine heat.
-
Enable True Four-Season Travel
Heating and climate upgrades make it possible to travel beyond warm months. With proper climate systems in place, your vehicle becomes usable year-round, allowing you to camp, ski, and explore in a wider range of conditions.
-
Improve Energy Efficiency
Modern diesel heaters and efficient climate systems provide consistent warmth or cooling while using minimal fuel or electrical power. This helps conserve energy, reduce battery drain, and extend time off-grid.
-
Reduce Moisture and Condensation
Proper climate control helps regulate interior humidity, reducing condensation that can lead to damp bedding, interior damage, or mold over time. This is especially important during cold or wet conditions.
-
Reduce Battery Strain in Cold Conditions
Cold temperatures can significantly reduce battery performance and available capacity. Proper heating and insulation help moderate interior temperatures, reducing battery strain, improving efficiency, and supporting more reliable electrical performance during cold-weather travel.
-
Create a More Comfortable Basecamp
Upgraded heating and climate systems turn your vehicle into a more functional basecamp. By maintaining a comfortable interior regardless of weather, you can prep for your adventures in comfort!
Overland Vehicle Heaters INstall & Service
White River Overland provides professional diesel heater installation and service for overland vehicles, delivering reliable heat for cold-weather and four-season travel. Our installs focus on proper fuel integration, safe exhaust routing, and efficient electrical connections to ensure consistent, dependable performance when temperatures drop.
Air Conditioning Solutions
Staying cool is just as important as staying warm. We integrate air conditioning systems and interior cooling solutions that support comfortable travel during hot weather and high-elevation temperature swings. Each setup is designed to work with your vehicle’s electrical system, battery capacity, and insulation strategy to deliver effective cooling without unnecessary complexity or excessive power draw.
Insulation, Thermal Management & Climate Efficiency
Effective heating and cooling depend on proper thermal control. We evaluate and improve insulation, heat retention, and overall climate efficiency to help stabilize interior temperatures year-round. By reducing heat loss in cold conditions and minimizing heat gain in warm environments, these upgrades improve system performance, reduce energy demand, and create a more comfortable, efficient overland vehicle.
Heater & Climate Upgrade SERVICES
If you’re building a four-season overland vehicle or want to improve comfort in cold or hot conditions, our team can help design a heating and climate system that fits your vehicle and how you travel.

ABEONA
The Abeona custom van was designed to be comfortable even on extended trips. It is loaded with creature comforts, like a stowable shower and a high-end kitchen complete with induction cooktop and coffeemaker. It’s powered by the SAGA 4V power system with a 9.6kW battery bank and 270W solar power, so it remains functional even for extended off-grid trips, and the advanced climate control system means it can be used all year round.

Wolf Den
The Wolf Den was designed to be a 4-season van for camping, skiing and cross-country trips. It can comfortably seat and sleep three passengers without feeling crowded. We particularly love the Bamboo paneling and Baltic Birch custom cabinets on this van build, and there is loads of storage incorporated into the design for gear and supplies.

The Zen Den was created for a family who wants to enjoy the best of both indoor and outdoor living while on camping adventures. We managed to get 5 sleeping spaces into the van by incorporating a rooftop tent and folding bench seat. The layout is highly configurable and slide-out rear kitchen saves space while allowing them to cook outdoors.

Meili
This van was designed for an active couple who loves skiing, so it was important that the van was equipped for icy roads and sub-freezing conditions. In addition to a fantastic heating and suspension system, the van has features like frost-proof plumbing so they can take a hot shower after adventures.
