In my 30's I often did 550-600 a day. Would get up at 6, drive for a couple of hours and stop for breakfast. Usually drove a 12 hour day. Wife usually drove for an hour or so after lunch to give my eyes a break. At the time you will be traveling CG's may be full by 4-5 pm so you'll need to reserve or use Wally World/truck stops.
Now, 45 years later it's 9-3 or 4. Only time we exceed 7 hours is out west where facilities are further apart. Each decade now seems to reduce our range a 100 miles or so per day. In scenic country we may only get 150 every other day. In retirement the journey is the destination!
