My wife had that same truck, same year in Teal we bought new , sold it with 123,000 miles on clock in 99.
I bought my Daughter a White 03 extended cab with the 3.0 , auto just before her senior year ( was a dealer demo )
sold that one to a neighbor down the road 3 years ago.
It had 130,000 then and it's still a daily driver for the guy. My sister had 220,000 on her 92 Explorer 4.0 , those V6 Ford motors have some legs.
Point is, keep it under you, and drive like own and care for it, rather than like you stole it and it will serve you very well.
