My last big rig was a KW, Cummins 400. I used to be able to save alot of money just watching where i bought fuel. I had two 100 gal. tanks, and would burn 100 gal or more per day. The difference in fuel prices, allowed me to save anywhere from $10 $20 a fill up. That savings would more than pay for my meals. That´s still true today, although my expediter tanks are half that capacity, so I don´t watch it as closely. I also have every motel discount card I can get, because I´m in a motel quite a bit, especially when I get caught in Noloadville on weekends. Then of course there´s meals. If you look around there´s always a deal somewhere. Just read the signs. An unknown is how much you save on maintenance costs. I spend the money to go the extra mile, and I think it pays off in the long run, big time. Example: if my batteries even cough, I replace them. If my starter skips a beat, out it goes. If a tire starts thumping..goodbye. Maybe extreme to some, but one tire bought in the wrong place because you "have to" could easily cost you double. Batteries too. I don´t deny myself comfort on the road, and if I have to idle my engine to that purpose, I do it. I try to watch my expenses to that end, comfort and profitability. Any tips i haven´t thought of, will be greatly appreciated.
