same here - I've got two boys at colleges in far N Georgia(Young Harris College) and far N Alabama(University of Alabama in Huntsville) where we like to visit several times each year, from west central Georgia - each about 300 miles away, each, and thru the mountains between the two, another 200+ miles.
Georgia has an expanding GeorgiaPower&Chargpoint DC Fast Charger network in some great areas in our pathways - such as Columbus, GA at Burger King, Lagrange, GA at ChicFilA, Emerson, GA at ChicFilA, Ellijay, GA at their Chamber of Commerce(near WaffleHouse and BurgerKing), etc.
ElectrifyAmerica has an expanding network with a row of pumps in Kennesaw, GA, a station at Walmart in Oxford, AL, and several in Ooltewah, TN(Chattanooga area) between the two boys.
We'll be towing our 2,500 lb Casita 17' Liberty Deluxe single-axle fiberglass camper, so we'll get some really good 'real world' towing experience along the way, and with the Tow Technology package and the Max Towing package. I don't plan on waiting until I'm at 0 battery power to hit a DC Fast Charger, but we'll also be able to Level 2 slow charge overnights at the campground, and at each boy's own camper lot, since they both live 'off campus' in their own Camper on a private 1 acre lot, in residential neighborhoods. Sweet. With the Pro Power Onboard we'll also have little need for 'lectricity' wherever we stop. Coming from owning and traveling in a large diesel pusher motorhome over 6 years and 110,000 miles across the country, Canada, and even Alaska, having 'easy to use' electrical power for the camper will make traveling a breeze.
Our 'round trip' for the journey should be close to 1,000 miles, including the beautiful BlackRockMountain state park campground, in MountainCity, GA, the highest state park in the state. We may even hit Cloudland Canyon state park campground in RisingFawn, GA, with almost the same elevation, or even CherokeeRock Village campground, Leesburg, AL. These will 'test' the truck and it's pulling power since all have very steep entrances to and into the parks. There will also be a good mix of high-speed interstates and regular speed roads along the way. We may also overnight at AmicalolaFalls state park campground, where there is an infamous 2 mile drive up the 25% grade road....no worries!
