At 1.00 per mile.........
Even if you get 11 or 12 mpg and 3.80 a gallon fuel your fuel cost would be about .33 a mile
$20 a hour for labor is another .32 per mile
That is .65 per mile
That gives you .35 a mile or 437.50 to pay for truck; motel and profit.
Food and other things comes out of your labor pay.
On the other hand...........
If you get caught hauling for hire with out the proper insurance and licence you may think $4 a mile was not enough.
