Hi Phil,
The most important thing is we know our bottom line. We know how much we need to make to break even and make a profit. If we can't make a profit we don't take the load, there are exceptions, like if we want to make a move to an area where there might be more freight we will take a load at our break even cost, and sometimes, but rarely lose a few bucks, but only if it is to our benefit to move. We watch fuel prices very carefully, it helped very much, especially when the price of fuel was really high. We have slowed down our speed. Slowing down our speed has increased our mpg by up to one mpg, this is a great money saver and costs nothing to do, just drive slower. We do not idle our truck. An APU is a necessity these days, the investment in an APU both extends your main engine life and saves you money by not having to idle your main engine. Weather permitting we shut down the APU and set it to auto start to keep out batteries charged. We check our tire inflation, this has saved us money both on mpg and tire life. We got over 165,000 miles on our steer tires. We make sure we do all our preventive maintenance on schedule. We have our APU oil and filter changed when we have the same done to the truck, even though it might not be time for the APU to be serviced. We figure the small extra cost is worth it, the small engine on the APU works hard so we figure the early service might extend the engine life. We eat more in the truck and less at truck stops, fast food joints and other places. One thing I should have mentioned at the beginning is that we spec 'd our truck to fit our needs and to earn the most money we could. We are a full WG CR T-VAL unit. We have every Clarence necessary to haul all freight FedEx CC handles. We chose to go with a class 8 truck with an automated transmission. We get the same mpg as most class 7 trucks do with the advantage of the class 8 engine and chassis. We also chose to go with a C unit. We have not noticed any decline in our income going with the C unit, and have four less tires to replace having just one real axle. We also make sure we have all scheduled maintenance done on the reefer unit. We have bought a set of Air Tabs, but have not installed them yet. When we do, we expect to increase our mpg. We are always looking for ways to be more profitable. We read industry publications, read the EO forums, talk to fellow expediters, we use any and all means to find ways to save money and increase our income.
