Climate Control That Works—Anywhere:

Why Our Expedition Vehicles Use Split AC + Diesel Heating for True Four-Season Comfort

When it comes to expedition vehicles, climate control isn’t just a comfort feature—it’s survival equipment. Whether you’re crossing the Mojave in August or waking up in the Rockies in the dead of winter, staying cool or warm isn’t optional. That’s why, unlike most RVs that rely on noisy rooftop units or propane systems with limited reliability, we’ve built every Wander Voyager rig with a smarter, more capable solution: a combination of residential-style split air conditioning and a powerful diesel heater—built for off-grid, all-season performance.

❄️ Residential-Style Split AC: Comfort That Doesn’t Compromise

Most traditional RVs use rooftop AC units that are loud, inefficient, and designed for intermittent campground use. In contrast, we equip all our expedition vehicles with a 12,000 BTU 110V mini split system—the same type of AC you’d find in a modern home or apartment. Why?

Because it’s quieter, more efficient, and better at temperature control. Mini splits allow for precise climate management inside the living cabin while maintaining a lower energy draw compared to typical RV units. Whether you’re plugged into shore power or running off your battery and inverter system, the 110V configuration strikes the perfect balance between performance and compatibility with off-grid setups.

And yes—it heats too. The built-in heat pump function provides warmth in moderate cold conditions, making it great for chilly mornings or cool evenings when you don’t yet need to fire up the diesel heater.

🔥 Diesel Heater: Rugged Heat for Harsh Conditions

While our split AC system includes a heating function, it’s not designed for high-altitude or sub-freezing temperatures. That’s where the 5,000W diesel heater comes in.

Unlike electric or propane options, diesel heaters draw directly from your vehicle’s fuel tank and are engineered specifically for extreme environments. They perform reliably at altitude, in snow, and in the coldest weather—keeping your cabin toasty no matter how hostile the weather gets outside.

Better yet, diesel heaters consume very little electrical power, so your battery bank stays charged even through long winter nights. They’re compact, quiet, and provide dry, circulating air that helps prevent condensation and moisture buildup—an often-overlooked benefit in cold climates.

🧭 Built for Real Off-Grid Use

Together, this climate control combo allows our expedition vehicles to perform far beyond the limitations of traditional RVs. Whether you’re heading deep into the mountains, parking by a frozen lake, or chasing desert sun, your Wander Voyager rig adapts to the climate—so you can focus on the journey, not the weather.
