That is a good comparison. You always have to plan for the next move. In addition, you must know what your cost per mile is. That is the most inportant number. It amazes me how many drivers don't really know what it costs to operate their truck. With fuel at or above $2.00 a gallon, this is a concept that folks should understand. I have seen time and again folks taking a 500 mile load, deadheading 200 miles to get it, and then deadhead 300 to the next location to wait on a load. At these numbers, you are running around for .60 to .70 cents per mile. Or in some cases, depending on the company, less. In most cases, you are simply going broke. Companies need to satisfy their customers and cover loads, and will at your expense if you allow them.
