New England to Northern Arizona

[BoldRuler]

Hi All,
Very grateful to be part of this forum. And I really appreciate the responses veterans give us noobs. I have never driven across country before. I've driven from Burlington, VT to Grand Rapids , MI and back in two days (14 hours each day) and I was the only driver. But this upcoming cross country trip is a big deal for me. I have limited time to spend in and around Sedona, AZ so I plan on taking two weeks off from work and would like to get from Vermont to AZ in three days. I'll have a second driver with me.

So here's my plan...

Day One: Burlington, VT to just past Columbus, OH (700 miles) I-90 to I-71
Day Two: Columbus, OH to Oklahoma City, OK (900 miles) I-70 to I-44
Day Three: Oklahoma City, OK to Sedona, AZ (900 miles) all on I-40

I understand its a lot of driving pulling maybe 13 hour days but with two drivers I feel it can be done safely. I'll be renting a car as my older CR-V might not be as reliable. I'm planning on leaving on a Saturday AM and would drive through evening of Monday on way there. I've just never made a trip like this before. I ask, what should I be aware of? Does my itinerary sound ok?

Anything the veterans here could offer would be most appreciated!
