I'm taking my first Tesla road trip tomorrow! Travelling from Maryland to Alabama, planning on taking the I-81 corridor. A perusal of threads here has given me a few tips. For example, EV Trip Planner has us charging in Knoxville just enough to get to Chattanooga and then spending a lot of time at Chattanooga. There are a lot of restaurants and other amenities in Knoxville while the Chattanooga supercharger is at an airport with the expected over-priced options. So we're planning on eating in Knoxville and then topping offf in Chattanooga to head into the supercharger desert in Alabama. Also, Wytheville to Knoxville is a long jump, I'll have to watch my range. What tips do you have for travelers along I-81? Thanks!
