EV Range Planning When Towing an RV or Trailer (2026)
Updated for 2026. Plan real electric-vehicle range when towing a trailer or RV, with towing loss, charging stops, and cost math at $4.06/gal gas and ~42¢/kWh public charging.

Electric trucks and SUVs tow surprisingly well, but range is the number that surprises new EV towers. A truck that shows 300 miles of range unladen can drop to 150–210 miles the moment you hook up a travel trailer. Plan for that loss before you route the trip, not at the first empty charger.
Direct answer
In 2026, expect an EV pulling an RV or trailer to deliver roughly 50–70% of its unladen range—a 30 to 50 percent hit from added weight and aerodynamic drag (estimates; real figures vary by rig, speed and weather). Budget charging stops around that reduced range, use trailer-friendly DC fast chargers, and cost the trip at ~42¢/kWh public charging (AAA, Aug 2026) versus $4.06/gal gas (AAA, Aug 2026) for a comparable truck. The federal EV credit is gone in 2026, so don’t subtract one from the purchase price.
Why towing kills EV range
Three forces stack up the moment you tow:
- Aerodynamics. A trailer or fifth wheel is a wall against the wind; highway speed above 65 mph hurts range far more than in a car.
- Weight. A 5,000–8,000 lb trailer adds rolling resistance and regeneration can’t recover all of it on rolling terrain.
- Climate load. Cabin heat or A/C and, for trailers, 12V compressor fridges draw from the same pack.
A useful planning rule: take the manufacturer’s unladen range, then plan on 50–70% of it while towing. If the route is mountainous or hot, plan on the lower end.
A simple towing range plan
- Start from unladen EPA range, not the guess-o-meter with a load.
- Apply the towing factor: ×0.5 to ×0.7 depending on trailer size and speed.
- Subtract a 10–20% buffer for hills, headwinds, and detours.
- Map chargers with pull-through stalls; many sites list trailer access.
- Recompute cost at your charging mix (home vs public).
Example: a 320-mile unladen EV towing a mid-size trailer at ×0.6 ≈ 192 miles; minus 15% buffer ≈ 163 miles between charges. That is your planning number, not 320.
Cost: EV tow vs gas tow in 2026
Energy math at 2026 prices:
- EV, home charging: ~0.17–0.18 $/kWh × ~2 kWh/mile towing ≈ ~$0.34–0.36/mile (estimate).
- EV, public DC fast charge: ~0.42 $/kWh (AAA Aug 2026) × 2 kWh/mile ≈ ~$0.84/mile.
- Gas truck at $4.06/gal (AAA Aug 2026), ~12 mpg towing: ≈ ~$0.34/mile.
The takeaway: towing on home power is cheap, but relying on public fast charging can cost about the same per mile as a gas truck. If you tow often and charge mostly away from home, run the EV vs Gas Camper Cost tool before assuming an EV saves money.

Estimates only. Towing range and efficiency vary widely by vehicle, trailer, speed, terrain and weather. The federal EV tax credit expired Sept. 30, 2025 (One Big Beautiful Bill Act); verify any state or utility incentive yourself. Not financial or engineering advice.
