The real cost gap: EV camper vs gas RV in 2026
Comparing an electric camper van to a gas motorhome is not as simple as "electric is cheaper." The answer depends on where you charge, because the price of electricity varies more than the price of gas. At home overnight rates, electricity is a bargain. At a highway fast charger during peak hours, the per-mile cost can approach or even exceed gas.
Use the calculator above to model your real scenario. The defaults use current U.S. average rates (EIA gasoline: $4.08/gal, home electricity: ~$0.14/kWh). Switch the preset to "Public fast charging" to see how the advantage shifts.
Example comparison: 500-mile weekend trip
| Scenario | Cost | Per mile | Notes |
|---|---|---|---|
| Class B gas camper van (18 MPG, $4.08/gal) | ~$113 | ~$0.23 | Most efficient gas option |
| Class C gas (12 MPG, $4.08/gal) | ~$170 | ~$0.34 | Typical family RV |
| EV camper, home charge ($0.14/kWh, 0.45 kWh/mi) | ~$32 | ~$0.06 | Cheapest scenario |
| EV camper, fast charge ($0.40/kWh, 0.45 kWh/mi) | ~$90 | ~$0.18 | Still cheaper than gas RV |
| EV camper, mixed 50/50 home/fast | ~$61 | ~$0.12 | Realistic for most trips |
These are operating costs only — fuel or electricity. They do not include rental fees, insurance, campgrounds, or maintenance. The EV advantage is largest when most charging happens at home or at campgrounds with Level 2 hookups included in the site fee.
Fuel prices are U.S. averages from the EIA (week of Aug 3, 2026) and change weekly. Electricity rates vary significantly by state and time of day.
