I make a 9-10 hour drive to see my family multiple times a year. I normally stop twice to get gas and use the bathroom, and that's it. Sounds like you'd be adding most of an hour to my travel time each way. I've tried stopping longer and grabbing food, it's not worth it for me.
With that said, I drive 25-40 miles a day the other 360+ days of the year, so it'd really make much more sense for me to have a short range EV and rent something for travel when I have too much luggage to fly.
