THIS IS NOT YOUR GRANDPAS RV! 2026 THOR FOUR WINDS 21Z
6 WELDTEC LIFT FOX SUSPENSION 1380Ah LITHIUM 600W SOLAR CUSTOM INTERIOR

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.

Permanent rear bed
Cab-over sleeping area
Convertible Dream Dinette bed
Full bathroom and kitchen
Interior and exterior storage
Factory-rated seating and seat belts for up to five
