Two of my semi tractors are nothing but trouble. I have spent piles of $$$$$$ hoping they are finally "fixed". Within a week or two they need more repair. One is down for the count with a busted crankshaft onlt three days after it got out of the shop. The other one just about burnt up Friday night. Seems the batt cable rubbed thru by the front of the air tank and started a small fire that went out only because it burnt thru the plastic air line to the tank causing a big release of air to extinquish the fire. I would be $$$ ahead just parking them.Any words of wisdom for me. Thanks, Bill
