Stop in for a cup of coffee

Cause I'd have to wait until I retire otherwise lol
Mathematically, if I average 55 miles an hour, I'd only have to average driving 4.5 hrs per day.....

4.5 hrs per day driving leaves nearly no time to see anything. Shorten the trip or take more time.

If you can't take the time, I would just do sections of it in successive years and see more. Take time to enjoy the trip.
