Me and a good buddy of mine are planning to have a 5000 mile road trip from Tennessee to Washington to meet a mutual friend. We've done most of the math, but we know road trips can be unexpected and surprise you, so I'm here to ask for pointers. The car we'll be driving is a 2001 Ford Taurus. It gets a good 35 mpg highway, so we've set aside roughly $500 for gas. But what other expenses would we need to account for? Where do we stay on the road that has good security so we don't get robbed or the car doesn't get stolen? We will be staying with our friend for a week or two before we drive the other 2500 miles back to Tennessee. What should we expect, as this is both of our first road trip? We plan on going late June through to early-mid July.
