Run it!!! I have run 16 hours at 65 miles an hours,, long haul but doable!! If you wanna go then go,, You and another driver should be able to run at least two tanks of fuel a run before driver change,, red Bull and Soda,, Snapple bottle and you keep a rolling!!! you have a bed, rotate when you get tired,, when you get fuel you get food,, GO!!! A four hour nap and your good for ten more..
If you are doing it for a living it will catch up with you,,, But if you NEED to be somewhere,,, GET THERE!!!
