Our family experience is that we stop about every 4 hours, usually limited by the size of the fuel tank. Because I have an EV and a gas car (gas car for road trips), I timed several of our fuel stops on a recent trip. Most were 11-14 minutes, measured from driving onto to off of the gas station property. I tend to do most of the driving, and 11 hours a day is around what I feel comfortable doing. That happens to be the door to door wall-clock time for our trip to my in-laws (766 miles). I'd pay a fair amount to avoid adding another 60-90 minutes to that trip.
