I don't want to stop for half an hour every 200 miles.
You might be able to do a gas stop in 5 minutes. I'm willing to bet that you can't do a gas stop and pee in that time. Two hundred miles is probably 3 hours of driving, so I am also willing to bet you want at least a coffee. Add five minutes (or more if you have to move your car). If you add in a snack, your total time will probably be around half an hour. A meal, make it an hour.
When I drive long distance, particularly by myself, I typically get on the highway with a full tank and pull off when my low fuel light comes on. Depending on traffic conditions, this is typically between five and six hours. At the end of that I don't mind stopping for half an hour or more, but that requires far more than 200 miles of range.
When I do stop in the middle for coffee and a leak, it's rarely more than 15 minutes total off the highway (unless the service is slow).
