Ok, I actually went back and revisited the numbers. I'm not sure how close my assumptions are, but probably not too far off.
Assumptions:
Avg. Fuel economy: 8 mpg
Driving time: 8 hr/day 300 days/year
Diesel fuel cost: $4/gal
Average speed: 50 mph
That works out to be $75,000 per year just on fuel. So 1% improvement (not 1 mpg, but 1%--0.08 mpg) pays back the trucker $7,500 per year.
