I’ll tell you what I do. You can choose what you think will work for you.
I have done several road trips of 2000+ miles. It’s very doable if you don’t rush.
Before you leave have your car checked out by a reiable mechanic, especially if it hasn’t been serviced for a while. You don’t want the hassles of a breakdown just because a $20 belt that’s seen better days decides to break. Make sure your tires, brakes, cooling system, fluids etc. are all in good shape. Minimize the chances that something will cause a breakdown on the road.
Get a reliable towing service in the event your car breaks down. You want one that is willing to tow you 50 or more miles if necessary. I chose Good Sam since AAA in my area will only tow cars about 5 miles max.
I load my phone up with audio books from my favorite authors. A good audio book makes time fly. Also download any maps for the areas you will be driving through. It’s not unusual to find no cell service on sections of highway.
Map out your route and plan your nightly stops ahead of time. I make hotel reservations if possible. Stick to major highways unless they are not practical. That’s where the services are you will need or might need in case of an emergency.
Bring extra drinking water and snacks in case of an emergency.
I have my drive routine. It depends on fast food joints for breaks. <— Warning!!!
I eat a lite breakfast then hit the road. After 90 minutes to two hours, I stop at the next McDonalds where I get out of the car, order a light snack (burger or egg McMuffin, and a beverage), I walk a bit and use the bathroom. The entire stop takes 20 minutes and I try to be on my feet for most of that time. Then off I go for another 90 minutes to two hours when I stop again. Repeat this all day until you get to your first night’s stop. I can go for 8 to 10 hours doing this. You did plot out where you will stop for the night right?
I can cover 450 to 600 miles a day doing this. More if I have a partner to do some of the driving.
