mine has 25965 miles on it. put maybe 30 gallons of premium fuel in it for its entire life, the rest was 87 octane. Tow trailers once a month. and change the oil every 500o miles.
So far i have had no issues. Except now it's stuck in low range

. but it is expected.
This week i'll get the tranny serviced and change the timing belt and pump.
I LOVE THIS TRUCK!!!!!!!!!!!
