For long range trucks (electric) there could be (in theory) yet another possibility, adding a trailer on the highways. Not entirely unlike existing multi-trailer (used on some roads in Australia), so called Road Trains, but limited to two trailers, the main one and the battery trailer: https://en.wikipedia.org/wiki/Road_train https://en.wikipedia.org/wiki/Road_train the truck would enter the highway, stop at a service station, add a "powerpack" battery trailer, drive until the next station, swap battery trailer as many times as needed, then leave it at the last service station before destination.
