I drove from Ft. Worth, Tx to Rohnert Park, Ca..........36 hours with just a 2 hour nap in Arizona.
On the short end, I did a 16 hour drive from Charleston, SC to Bethpage, NY......only took that long cause I got lost up in NY. On the way back, it was only about 13 1/2 hrs.
We do 6 to 7 hour drive every now & then from Charleston to central Florida.
I would have to say rhe longest I have ever driven without sleep of any kind was the 24 hour drive from Ft. Worth, Texas to Ocala, Fl.
