2026 THOR FOUR WINDS 21Z
6” WELDTEC LIFT • FOX SUSPENSION • 1380Ah LITHIUM • 600W SOLAR • CUSTOM INTERIOR
THIS IS NOT YOUR GRANDPA’S RV.
This nearly new 2026 Thor Four Winds 21Z has been transformed from a standard Class C into a lifted, solar-powered adventure rig built for extended travel, boondocking and remote work. It combines the comfort of a modern tiny home with an aggressive expedition-style stance.
Highlights include a 6-inch WeldTec lift, FOX suspension, Toyo all-terrain tires, a professionally organized 1380Ah heated lithium system, 600W of rooftop solar, Starlink Mini and a fully customized interior. The RV comes stocked with linens, pots, pans, flatware, bowls, plates and other essentials.
LIFT, SUSPENSION & TIRES
• WeldTec 6-inch suspension lift
• FOX shocks and steering stabilizer
• Carrier-bearing drop
• Toyo Open Country A/T III 285/70R17 tires on all six wheels
• Spline-drive lug kit
• Ford E-Series rear-wheel-drive dually chassis
• Added fog lights with interior control switch
• Professionally tinted front windows
These upgrades give the RV a taller, more aggressive stance and set it apart from virtually every stock Four Winds on the road.
HIGH-CAPACITY OFF-GRID POWER
This is far beyond a basic dealer-installed solar package. The professionally organized system is designed to support extended off-grid use while dramatically reducing generator time.
• 1380Ah total lithium capacity (approx. 17.7kWh nominal)
• Three 460Ah Epoch Essential heated lithium batteries
• Victron MultiPlus-II 12/3000 inverter/charger with 3000W output
• 600W rooftop solar: three 200W flexible panels
• Victron SmartSolar MPPT 250/75 controller with up to 70A regulated solar charging
• Two Victron Orion XS 50A DC-to-DC chargers providing up to 100A of managed alternator charging while driving
• Shore-power, alternator and solar charging
• Victron Cerbo GX MK2, GX Touch 70 display and SmartShunt battery monitor
• Bluetooth monitoring with real-time battery, charging and consumption data
The system can power standard 120V outlets and appliances from the battery bank. Major components and wiring are protected inside a ventilated, serviceable custom enclosure in the rear storage compartment, with everything cleanly organized and labeled.
The original 4.0kW onboard generator remains fully operational as a backup for high demand, poor weather or extended use. A Starlink Mini has also been added for connectivity while traveling or working remotely.
CUSTOM INTERIOR
The generic factory-RV look has been replaced with a warm, residential feel:
• Custom solid-walnut slab dinette table with hand-finished epoxy top
• Brown leatherette dinette seating
• Blue refinished cabinetry
• Custom wood window valances
• Updated finishes and bathroom accent wall
• Custom-matched electrical switch and control panels
• Laveo Dry-Flush toilet
The original toilet was replaced with a self-contained Laveo Dry-Flush system, which seals waste in disposable barrier material to reduce odor and eliminate regular sewer hookups. It is especially convenient for boondocking, cold-weather travel and faster departures. The original factory waste tank remains installed.
COMPACT, NO-SLIDE LAYOUT
At approximately 24 feet long, the 21Z is easier to drive, park and maneuver than a large Class A or oversized Class C. With no slide-outs, there are no slide motors, seals or mechanisms to maintain, and the entire interior stays accessible while closed.

• Interior and exterior storage
• Factory-rated seating and seat belts for up to five
