Truck has 138k miles since inframe. Until the drive-shaft problem, truck running great. Fuel mileage finally came back and it has been breaking all new fuel mileage records with it. Still afraid to change those last 3 injectors or any of the fueling/timing actuators (have more than 1 mil on them now) because fuel mileage is so good.

Truck is breaking 9.5 mpg with 20,000 lbs in the trailer, 8.5+ is not unusual with 80,000 and touching 17 mpg bobtail on occasion.

Only signs of "newness" left from the inframe is when it sits and engine gets cold. It will still make an occasional tiny white puff of smoke at the exhaust at first crank but other than that no signs of anything. no measurable oil consumption at 15k miles after oil change and certainly no blowby out of the oil fill cap like that video posted above.
