Southeast New Mexico isn’t always an easy place to visit in an EV. The big thing is that it’s oil country, just like west Texas . Until just very recently, it was a total EV dead zone, even if you own the longest range Teslas. Even the vaunted Supercharger network dared not tread into the area yet.
The other ICE strategy is to guess how far the car will go and then plan to visit some gas stations when the car will probably be getting low. In an EV, the EPA range figure might be close on some drives, but way off on others. Things like weather, steep hills, and speeding can make you fall way short of the EPA guesstimate . With a gas car, that mistake means finding a station sooner. With an EV, it could mean calling for a tow.
Finally, if an app says you can’t make it, don’t be afraid to spend a night charging slow somewhere to fill in the gap and keep the road trip going. Some hotels have charging, but other options like RV parks can be trip-savers on the back roads.
