I deal with fuel more than the average motorist who goes to Gilboa...
In a big truck, you're buying fuel for fuel tanks with 300 gal capacity (2 150 gal tanks). The most I've ever bought at one time is about 225 gallons. But we only get... 5.2 mpg- some trucks claim to get as high as 10 mpg. But the new emissions requirements are making high fuel mileage a thing of the past- I know drivers getting as low as 3.7 and 4 mpg.
So... doing the math (math in public- not a good idea... plus I just had a beer)... if you've got a 100 mile round trip, which is roughly what I've got, at 17 mpg in my SUV, and if fuel is $1.50/gallon higher than it was last year (which it's not), the extra $1.50 adds $8.82 to my trip.
Compared to the cost of gear, tanks, entry/parking, eating out etc, the extra fuel is not going to affect me at all.
Now, with the truck, we're paying up to $4/gallon for diesel. Compared to $3 diesel, which was hard to handle, that's killer. A 2,000 mile trip at 5.2 mpg costs us $384 more at $4 than it does at $3/gal. I have actually written several fuel checks for more than $600- California gold (and Arizona gold, and Washington State gold...).
Prepare to pay more for your goods, folks...
