I am planning my first real road trip. I will be alone both ways, am leaving tomorrow, and have a budget of $770. Also, I would like to be back by the 24th (26th latest). I plan on spending a maximum of two days in Phoenix. My car gets an estimated 19MPG. As far as capacity, I have driven six hours with minimal downtime but have never found a need to drive further than that (I was extremely bored by the drive, not really tired).
Is my budget too low?
At what intervals should I rest?
What preparations should I make?
Thank you. :)
