290,000 this past weekend, bought new (200 miles on it) in 1995, been my daily driver ever since. Not a better truck on the road (in my opinion).
note, not a true reading, as I have had 32" and 31" tires on it for most of its life, they turn slower than stock size, so I have come up with a formula.
current milage, - 30,000 (life of original 215 tires) than multiply by 12% (average between 31" & 32" tires) then add back the 30,000.
