7500 miles @ 20 miles a gallon @ $3.00 a gallon is around $1200. As far as food and water, I will be buying 24 packs of waters at grocery stores and drinking that instead of soda. I will be eating alot of Subway and small off road diners that are cheap.

I have the 7500 miles of driving that I need to worry about.

I am planning on taking a trip around the United states and also stopping through Toronto. Here is a little map of where I am going. If anyone has taken a road trip around the US, any advice is appreciated. I am looking to spend less than $3,000 and do it in less than 4 weeks.
