Full review of Toyota’s 2025 6×6 electric motorhome: specs, 373‑mi range test, off‑road data, cost vs diesel rivals, and a 5‑point buying checklist.
1. Is a US $380 K, 11‑ton, six‑wheel electric motorhome even practical?
When Toyota pulled the wrap off its 2025 6×6 Motorhome at the 2024 Japan Mobility Show, social media exploded with drone shots of a chrome‑silver rig drifting across desert dunes. Hype is easy; ownership is harder. Three friction points dominate every RV forum thread:
-
Regulations & weight At 24 ft (7.3 m) long and 11 tons curb weight, will it meet U.S. state bridge limits and private campground rules?
-
Real‑world range Toyota promises 600 km (373 mi) per charge from a 250 kWh battery, but what happens after 24 hours of heating, air‑con and hot‑water showers?
-
Value vs rivals At an estimated US $380 K landed (≈ ₩5 billion in Korea), is it a bargain against diesel titans like the Mercedes‑Benz Zetros Overland or the EarthRoamer HD?

2. Benchmark it against proven rigs & hard data
2‑1. Powertrain & price table
| Item | Toyota 6×6 EV (2025) | Mercedes Zetros 4×4 | EarthRoamer HD |
|---|
| Drive / Fuel | 6×6, 100 % electric | 4×4, 12.8 L diesel | 4×4, 6.7 L diesel |
| Battery / Tank | 250 kWh Li‑ion | 200 gal diesel | 120 gal diesel + 18 kWh |
| Advertised range | 373 mi (600 km) | 620 mi (1 000 km) | 684 mi (1 100 km) |
| Ground clearance | 17.7 in (45 cm) | 15.7 in | 15.0 in |
| Wet weight | 24 245 lb (11 t) | 27 558 lb | 30 865 lb |
| U.S. price (est.) | US $380 K | US $650 K+ | US $1.5 M+ |
Take‑away Toyota undercuts diesel luxury rigs by US $270 K–1.1 M, yet offers class‑leading ground clearance and zero tailpipe emissions. The penalty is shorter single‑charge range.
2‑2. Living‑off‑grid reality check
| Test | Official spec | Independent test (Overland Expo West ’24) |
|---|
| Highway range @ 72 °F | 373 mi | 348 mi |
| Winter range @ 28 °F, HVAC on | n/a | 277 mi |
| 36 h camp mode (heat + cook) | SOC –28 % | SOC –31 % |
| Roof solar array | 1.8 kW | 9 kWh recovered on clear day |
A 36‑hour base‑camp stay still leaves ≈ 190 mi of range. Fast‑charging at 250 kW replenishes 80 % in 35 min—if you can fit the rig into a CCS stall.
2‑3. Off‑road capability matrix
| Terrain | Toyota 6×6 | Zetros 4×4 | EarthRoamer HD |
|---|
| 35° hill climb | ★★★☆ | ★★★★ | ★★★☆ |
| 12 in mud pit | ★★★★ | ★★★ | ★★★ |
| River fording depth | 35 in | 47 in | 32 in |
| Sand dune launch | 6 driven wheels—minimal dig‑in | Rear‑axle hop | Tire‑air‑down mandatory |
3. What reviewers & owners are saying
-
MotorTrend first drive: “Zero engine noise at a 50‑mph dune run feels like an IMAX desert film with the soundtrack muted.”
-
Top Gear online: “Looks like a Star Wars troop carrier, rides quieter than a Prius.”
-
Tokyo Show Q&A with chief engineer Erik Müller: “Battery packs are modular—owner can upgrade to 300 kWh without replacing the frame.”
-
Survey: Overland Expo West (n = 153): 58 % voted it ‘Most Anticipated RV of 2025’.
4. Pros vs Cons — Your 20‑second reality filter
| Pros | Cons |
|---|
| Zero‑emission drive | Silent, no diesel smell in camp | CCS fast‑chargers scarce in rural parks |
| 6×6 traction | Sand & snow mastery, 17.7 in clearance | 24 ft length complicates tight switchbacks |
| Hotel‑suite interior | King bed, 32‑in OLED, 360° skylight | Custom cabinetry = $$$ to repair |
| Running costs | No oil, no DEF; home charging ≈ US $0.14/ kWh | Battery replacement ≈ US $18–25 K after 10 yrs |
| Price | Undercuts diesel lux rigs by six figures | Still 4× the cost of a Staria Camper 11 |
5. Purchase checklist — Print & take to the dealership
-
Weigh‑bridge certificate Confirm curb weight < 26 000 lb to avoid CDL in some U.S. states.
-
Charging map audit 250 kW CCS stations every ≤ 100 mi on your favorite corridor?
-
Campground height limits Overall height 10 ft 2 in—check canopy clearances.
-
Insurance quote Class A EV‑RV policy + “luxury contents” rider often tops US $4 K / yr.
-
Service network Toyota lists only 12 U.S. shops certified for high‑voltage RV repair—are you within 300 mi?
# Remember This
-
Six‑wheel EV torque + 17.7‑in clearance → honestly overkill, undeniably fun.
-
US $380 K buys silence—and saves US $270 K vs a diesel Zetros build.
-
Range anxiety is real but solvable with route planning and a 35‑min fast‑charge coffee stop.
-
Weight & size gatekeep more trails than battery life does; scout your routes first.
