Several trips from Manchester, Ia to Zapata, Tx 1385 miles. Would usually stop and take about an hour nap. 21 to 22 hrs driving time.
Trips to Yankeetown, Fl 1265 miles always drove straight thru. No land speed records but once 18 1/2 hours for my dad's open heart surgery.
In recent years, many trips to Durant, Ok 800 miles. Consistant 12 1/2 hours. Although since I have the teardrop it now takes me three days
