After putting a couple of thousand miles on my truck, feeling
it out, getting to know it, looking things over and feeling comfortable
w/ my tires, drivetrain et al, alone, I decided to see what it would
do on flat ground pedal to the metal, no headwind, w/ rear canvas.
I was probably running 1TON over dry weight . Air was COLD.
No other souls around, middle of nowhere, straight flat road.
The GPS said consistently I was traveling at 68.2MPH,
indicated was about 58/59 MPH. 23XX RPM
It runs incredibly smooth. I noticed driveshaft balancing
weights the other day crawling around under there looking
for the sorce of minor leak or two and looking for issues
general in nature.
I got lucky. I would jump in this truck
and hit it to Alaska (if someone gave me a gas card! )
