That's some drive.
How often do you stop for a break?
Here in the UK if driving at night in the rain and heavy traffic I find after 3 hrs is about right to pull over and stretch the legs. It just takes a moment and tiredness can change your and/or others life.
Obviously a lot of factors can change, age, experience, car, weather, type of roads, how much sleep one has had, been in the fresh air all day etc etc.
I remember driving on NZ's south island for 9hrs straight and thought I'd been driving for 4! Pacific highway was excellent.
I only drive during the day although I do tend to be out the door by 6:00 am
I tend to stop every 2-3 hours for a call of nature and a drink, coffee or snack.
It's great having the fridge in the back with plenty of water, strong nitro coffee and some cold meat and salad.
Plenty of bakeries along the way so a nice fresh bread roll or two so I can make a cold meat and salad roll.
I am the world micro sleeping champion so I often have a 10 minute nap.
The roads are pretty rough with lots of potholes, washouts and damage due to the huge amount of rain and flooding lately.
Not to mention the regular stray, cattle, sheep, goats, horses, camels, kangaroos, wombats, emu's and birds playing chicken with cars.
The Grenadier is just so good for this kind of trip.
I have ordered some new gear and will do a complete rear fitout over the next couple of weeks.
Make the loadout better and a lot safer.
