Compact enough to explore well beyond the interstate, but equipped with the systems of a much larger expedition vehicle, this 2023 Rossmönster Baja Trail is built on an F-350 Lariat Crew Cab 4x4 and designed for genuine four-season travel. The hard-sided power-lifting roof keeps the profile lower on the move, then opens into a bright habitat with generous headroom, panoramic ventilation, walnut surfaces, a convertible dinette, and direct cab access. Underneath, LiquidSpring suspension with Tru-Earth automatic leveling, 37-inch Falken Wildpeaks, Method wheels, a HoneyBadger bumper, WARN winch, onboard air, and Baja Designs lighting support travel beyond pavement, while an 800Ah lithium bank, 400W solar array, 3,000W inverter, Aqua-Hot hydronic heat, heated floors, rooftop A/C, Starlink, and integrated Bluetooth controls make extended stays away from hookups far more comfortable.
- Rossmönster Baja Trail Four-Season Habitat: The Baja Trail’s hard-sided lifting roof is a major part of its appeal, keeping the truck relatively compact while driving and creating a much larger living space at camp. Seven opening windows in the raised section, two Arctic Tern windows, an insulated composite shell, and a cab-to-camper pass-through give the interior an unusually open feel for a truck-based expedition platform.
- LiquidSpring With Tru-Earth Leveling: A 4-inch LiquidSpring suspension system transforms the chassis side of the build, adding a more sophisticated ride-control setup than a conventional heavy-duty truck suspension. Tru-Earth automatic leveling also handles campsite setup without blocks, ramps, or repeated repositioning.
- Built for Self-Sufficient Travel: An 800Ah lithium battery bank, 400 watts of rooftop solar, 3,000-watt inverter, Aqua-Hot hydronic system, heated floors, Eberspächer rooftop air conditioning, Starlink, and Bluetooth-enabled system monitoring give the Baja Trail the systems capacity to spend meaningful time away from shore power and established campgrounds.
- 37s, Recovery Gear, and Expedition Hardware: The F-350 rides on 37-inch Falken Wildpeak all-terrains mounted to Method Race wheels and adds a HoneyBadger front bumper, WARN Zeon 12-S synthetic-line winch, Baja Designs lighting, ARB onboard air, AMP retractable steps, full-size rear spare, exterior storage, and three large rear MOLLE panels. It looks substantial because the hardware is substantial.
- Well-Documented, Well-Traveled Build: The owners are moving toward full-time travel and stepping into a larger expedition platform rather than selling because the Baja no longer fits their needs. Build documentation and service records are available, and the rig is currently at Rossmönster headquarters in Longmont, Colorado for prospective buyers to inspect.
About the Rossmönster Baja Trail
Rossmönster’s Baja Trail takes a different approach from a conventional slide-in camper or large expedition body. The lifting hard-sided roof allows the truck to retain a lower travel profile while still creating a legitimate standing-height living space at camp, and the habitat is integrated directly with the chassis rather than treated as removable cargo.
That makes the Baja Trail particularly appealing for buyers who want four-season comfort and substantial off-grid capacity without moving into a full-size commercial expedition truck. This example leans heavily into that formula with LiquidSpring, 37-inch tires, recovery equipment, a large electrical system, hydronic heat, air conditioning, Starlink connectivity, and a detailed custom interior.
