Offered for sale is a Rossmonster Baja build of a short-bed pop-top camper on a loaded 2021 Ford F-250 Super Duty Lariat 4×4. This rig was purpose-built for serious off-grid adventure travel — and the build quality, component selection, and attention to detail reflect exactly that. It is being sold only because the owners are relocating internationally.
VEHICLE: 2021 Ford F-250 Super Duty Lariat 4×4
The foundation is Ford’s legendary 7.3L “Godzilla” V8 paired with a 10-speed automatic, 4×4 drivetrain, and 4.30 electronic-locking rear axle from the Tremor Off-Road Package. The suspension has been upgraded for improved off-road performance, and the truck rides on Kenda Klever R/T 285/75R18 all-terrain tires on black wheels. Up front is a custom off-road bumper with a front-mounted winch and dual Baja-style amber auxiliary lights. Dual awnings (one on each side) and an aftermarket hitch round out the exterior.
Inside, the Lariat trim delivers a genuinely premium experience: Oxford White over black leather, heated and ventilated front seats with driver memory, dual-zone automatic climate, SYNC3 8″ touchscreen, an upgraded B&O 10-speaker audio system, backup camera, and cruise control. Six upfitter AUX switches, a 110V/400W outlet, trailer brake controller, and LED bed lighting complete the package.
CAMPER: Rossmonster Baja (Short Bed Pop-Top)
The Rossmonster Baja is among the most well-engineered truck campers on the market. The motorized pop-top raises to full standing height at the push of a button and lowers flat for highway driving. A full-width LED light bar runs across the front. The white fiberglass exterior is clean and solid, with MAXTRAX recovery boards on the driver’s side and a rear exterior utility compartment with external access. The camper walks through directly from the cab via a canvas passage.
Kitchen & Water The kitchen punches well above its size. The True Induction single-burner cooktop is flush-mounted into the dark countertop. An Indel B 12V compressor fridge drawer sits below, keeping food cold silently and efficiently. A Rixens under-counter hot water heater provides hot water on demand at the stainless steel sink, which features an integrated bamboo cutting board. Fresh water storage totals 30 gallons. The rig is equipped with both an indoor shower and an outdoor shower — a setup that dramatically expands comfort whether you’re at a campsite or deep in the backcountry.
Sleeping & Living The upper sleeping loft accommodates 3 adults or 2 adults and 2 children, and features quilted insulated wall panels, individual reading lights, and a skylight vent above the bed. Access is via illuminated bamboo step stairs with warm LED accent lighting. The lower living area features a Lagun folding dinette table with padded bench seating on both sides and generous under-bench storage and converts to sleeping space.
Electrical & Power This is where the build truly shines. The electrical system is built around a Victron Energy backbone: dual Orion-Tr Smart 12/12-30 isolated DC-DC chargers keep the lithium house batteries topped up from the truck’s alternator, while 600 watts of solar panels provide primary off-grid charging. A Victron battery monitor displays state of charge in real time. A 3,000-watt inverter handles AC loads. Shore power connection and generator capability round out the charging options — this rig can camp anywhere for as long as you want.
Climate A Rixens furnace controller manages the heating system with multiple source options (engine heat, electric, and furnace/gas). A MaxxAir powered roof vent fan with handheld remote provides ventilation and cooling. Multiple vented windows ensure airflow throughout, and both fixed and passable skylights bring natural light into the living space.
