Just got back from an unplanned 1400 mile (2200 km) road trip in a Nissan Leaf. It was… mostly fine? We spent more time wrangling kids than waiting for it to charge, fwiw. August heat plus a passively cooled battery did mean we got throttled to just 20 kW for a few charges which was annoying, but again didn’t ultimately cause too much strife.
I wouldn’t recommend a Leaf for road tripping, but an EV with an actively cooled battery (and a bit more range) would be totally fine.
