All vehicles get worse mileage when towing. 50% to 65% of normal mileage is typical whether gas or EV (depends on tow vehicle, trailer type and weight, and road conditions).
Some gas vehicles have very large gas tanks – hah hah – while with others you may stop and refill the gas tank often during the day.
You can refill with EVs too – but recharging an EV with a trailer has 2 problems.
- Depending on EV, the charging port, and the charging station – in most cases, you need to unhitch the trailer to get the charging port close enough to the charging station cable.
- With an EV, like with a gas tow vehicle, you have to “refill” often – but refilling an EV takes more time – 15 to 30 minutes typically. That’s not much of an issue on a normal day trip – you charge up while eating lunch, for example – and do it once or twice during the day. But when towing, you may have to do this 3 or 4 times.
Another problem is that here in the west, there is generally no EV charging infrastructure within reasonable distance of USFS, BLM and NP campgrounds – yet they often have gas stations. I have not heard any proposals for dealing with this.
Note – I have a Ford Escape and a small Scamp trailer. I also have an EV.
