i'm planning a trip to the grand canyon with a buddy. neither of us have ever planned a roadtrip of this magnitude. we need to get there as soon as possible since we only have a week and i want like three nights hiking and camping at the canyon. google earth has it at about 29 hours of straight driving. we obviously were going to take shifts driving and sleeping. there is some concern of my 2001 focus with over 35k and the driving conditions as i get out west. any general advice would be welcomed.
