I have been able to quantify how much fuel the A/C uses, at least at idle. At no load the truck uses 1/4 gallons per hour. With the A/C max going it uses about 1/3 gallons per hour. That would explain why I'm seeing increased fuel economy at slightly reduced speeds.
So we're talking like a 10th of a gallon per hour increase.
