Unless they're going to be doing the reverse pony express by changing drivers the truck could be recharged while the driver is pulled over to rest and eat.
This trucking company says for drivers to assume 500 miles per day. So, unless you're going from 100% charge to 0% charge and assuming the risk of running out of charge before you get to your destination, that won't fly. and, this doesn't account for the fact that truck drivers will also drive to the limit of their hours, then pull over on the side of the highway to sleep. no charging station there.
