Several reasons for the semi getting the milage it does versus the pickup.
The semi is only turning about 1200 -1600 with wot @ 1800-2100. Peak torque in the semi is around 1200 peak HP is around 1600. Torque in the semi is around 1500-2050 depending on engine and computer settings. Hp is in the 400-600 range.
The pickup is turning about 2600 RPM or more. Peak torque is about 1400-1600 Peak HP is around 1800-2200 Torque in the pickup is about the 280-450 range HP is about 180-300 These are rough specs with no tuners,chips or what have you. So with more rpm's to make the power you get less engine efficiency. The engine has to work harder to meet the demand on it. The Part that always amazed me was the fact that with the difference in tire diameter the rear axle ratios were so closely the same. Semi's from 4.33 - 3.36 pickups from 4.10- 3.55 depending on axle manufacturer.
