it's 12 hours between my family in Ga and my family in Michigan. can't count the number of trips I've made bouncing back and forth. you'll do fine. pack snacks, take breaks. nothing to it. if you're sleeping in the truck and it's freezing cold outside, bring a real sleepingbag and pillow. and don't be afraid to idle the truck all night if you have to. I think that Toyota burned a couple gallons over 6 hours? I'd make sure I had a full tank though, just in case.
do not drive tired.
