Hello and welcome to R.T.A.

Do you mean 5 days each way for your trip or in total. With a bit over a 4000 mile round trip you will be on the road for about 9 hours a day for 8 days with short stops so you will have the evenings and a couple of days to do some short detours along the route.

We generally recommend covering 500-550 miles a day max [9-10 hours] for multi day trips so it would be a good start to see what area this will put you each night and what around there appeals to you.
