i am planning on driveing my 97 jeep wrangler with a 4.0 and a 5 speed from seattle washington to charleston south carolina. my question is that this thing has about 150,000 miles on it. do you think i will make it. i havent had many problems with it since i bought it. i am planning on changing the oil, the serpentine belt. do you think i will have any problems and what do you estimate my total gas price will be for this one way trip? plus what do you think i should bring with me for any emergency i may encounter.
