scoobydugan recently asked a similar question in a quest to get back to NY, which prompted me to get out the old calculator to work out how long I had gone without serious sleep whilst driving or working. I once did a 24 hour shift when I worked for a iron ore mining company.
But, back in the days of my long distance truck driving, I carted livestock for a living from the north-west, of West Oz.
My base was just over 1300 kms from Perth, where the livestock markets were. These markets closed at 8.30 am, Wednesday mornings. I had 2 loads to go from home base, and a 3rd from a station about 250 K's closer to Perth. I began my first run on Saturday afternoon, about 6pm. I finished the last trip, at the markets just before the 8.30am closing time, Wed.
Total Hours on the road:110 hours
6200k's or 3875miles total distance
1328k's or 830 miles per 24 hour day
Trucks maximum speed was about 105 kph
Rest stops included refuelling, meals, loading and unloading.
If you add 10 hours of daylight for the Saturday, it actually was 120 hours with minimal sleep. Nowadays, there is no way I could acheive that.
All one up. No co-driver. Oh and only poor radio reception!
