Hmmm, I'm a brand new Model 3 owner and I need to make it from Columbus, MS to Oklahoma City....If it was just me, I'd probably charge to 100% in Little Rock and drive 55mph for the 350 miles to OKC...not sure how my wife would feel about that though!
Edit: Looks like there is a destination charger at the Super 8 in Russellville, AR that is about 270 miles from OKC. That should work with a 100% overnight charge as long as we don't have a strong Oklahoma headwind.
