How bad are 4WD pickups?

My 13’ tall, 20,400-lb 579 Peterbilt semi tractor (13L Paccar with 10-speed Eaton AMT UltraShift) can hit in high 13’s to low 14-mpg while bobtail at 64-mph. Very first test I gave it.

I can let go of the steering wheel for extended periods (where periods can be fractions of seconds). Even several seconds. A vehicle that on a three-count is headed into the ditch is dangerous.

You’d (anyone) best believe that tire design, pressure and no-fault steering are huge contributors to MPG
