My first real time to surrender to the fact that the Prius was the superior tool for the job. The Facts: 306 mile round trip with about 6-7 hours at the destination Interstate almost the whole way No, and I mean absolutely none, public charging in the destination city (Jefferson City, MO--yes, the state capital !) Morning temps 7F, afternoon up to 23F I've done the trip before and was successful with a 2 hour charge at an RV park on the way back, but in warmer weather and only a 2-3 hour turn around time. I estimated at least 3 hours and up to 4 hours charge stop would be necessary due to the cold and that would mean I didn't get home until 10pm. I just couldn't do it. There are no public or private chargers listed along the route of travel on any of the major EV charger apps. The Prius did great, got me back in plenty of time for dinner with the family. Need some Superchargers in MO in a major way!
