The ultimate four-season luxury camper van: a Bi-Slide bedroom, shower, sauna, and outdoor kitchen engineered for serious off-grid adventure without sacrifice.
The TitanVans Ultra 144 is TitanVans' top-tier conversion, built around a Bi-Slide bed, an onboard shower and sauna, and outdoor kitchen access. It is designed for travelers who want a full-featured, four-season capable camper van without compromising on comfort or off-grid function.
Builds start at $160,454, reflecting the premium components and craftsmanship involved. The TitanVans Ultra 144 is built on either the Mercedes Sprinter or Ford Transit chassis, depending on the configuration selected, and every build includes TitanVans' EX3 electrical system.
That system is rated to function in temperatures as low as -5 degrees Fahrenheit, making it a genuine four-season option. RVIA certification and Mercedes-Benz eXpertUpfitter recognition back up the build quality.
This model suits couples or solo travelers who prioritize amenities like a shower, sauna, and outdoor kitchen alongside serious off-grid electrical capability. It is a strong fit for extended trips in variable climates, from desert heat to mountain cold.
