Hey Guys,

I am doing a road trip this weekend to St Louis to visit my childhood best friend who is dying of cancer. I was going to take a flight out there but decided to take the road trip in order to clear my head before seeing him as this is painful for me.

From where I am (Bronx NY) it's a 15 Hour drive. So I am seeking information from those of you who have traveled far in our cars (X5) and tell me what should I take with me, what preventive maintenance I should do to the car. I will be leaving Friday 11pm. The most I've ever driven is 9 hours, so I know I will need to stop a few times.

Any information will be amazing...

Thank you in advance
