Driving from Nashville to Phoenix: I-40 or I-10?

Getting ready to move my mother across the country. Sometime in the next few weeks I’ll be picking up a Uhaul in Nashville, heading back to Phoenix loaded with a bunch of her stuff.

Which route would you choose? This will be a turnaround trip. No time for sightseeing. Just trying to avoid delays of construction and traffic. I doubt weather will be a factor this late in the season.

I-10 adds a few miles, and there’s the challenge of getting to it through the DFW mayhem.

The last time I drove I-40, ALL of Arkansas was one giant construction zone.

Anyone who’s traveled either of these routes recently, please opine.
