If you only stop once from Abilene to Sacramento, it's probably going to be in Arizona, maybe near Flagstaff? Maybe start with this itinerary: https://www.trippy.com/drive/Abilene-TX-to-Sacramento-in-2-days I would add an overnight stop at Flagstaff and remove the overnight at Petrified Forest. That gives you about 14 hours of driving each day, which is doable. Start driving around 6 or 7am, and only rest for about half an hour at each stopping point, and that should get you in before 11pm each night.
